Ok I'm having a problem i have tried a bunch of different things (I have searched across the site and i can't find anything about this exact problem)
I have a 2000 sunfire sedan 2.2L
Ok so in the summer i changed my front turn signal lights to white LED (3157 with 12 led bulbs) bulbs that are the brand EUROLITE (stock bulbs in rear signals still)
They work fine except that they blinked too fast so a bought a EP27 LED flasher that fixed my problem they work like any normal bulb would
now here is my issue:
I bought two MORE led (3157 12 led) in red because i have clear TYC/APC taillights (the ones with no reflector) that i would like to use but i need a red bulbs for them
So i installed the two NEW led's to complete all the signals with LED's (Front signals and rear signals)
It works perfectly fine with my headlights/interior lights totally switched off...but as soon as i turn the headlights/interior lights on the signals wont work...
it doesn't make a buzzing noise or anything its just silent it will click once like it does when its flashing then it goes silent and the signal light will stay on
I haven't touched any stock wiring or anything
Hazards still work...
What i have tried/ruled out:
Flasher...My Flasher is the EP27 for LED's and it is in working order
Switch...i switched the rear bulbs back to regular stock bulbs and it still works fine
People have said the it might be overloading but that doesn't make sense to me due to led's usually drawing less current than standard bulbs?
IF someone can help me that would be greatly appreciated! I'm sorry if this question has been asked i couldn't find it in multiple searches i did...I found some hints to try but nothing worked
Please help me

it's more not loading enough than the overloading, hahah. just run stock bulbs up front and the red LED's on the rear Nikki.
What i had tried to say in chat was think of it this way:
standard bulbs, one goes out, the other blinks really fast = less resistance, more amperage through the breaker, trips it quicker
you said you replaced the front 2 with LED's, similar problem, blinked too fast = less resistance, trips it quicker
you swapped out the flasher with just that setup there, fixed the problem with the front 2 LED's, the breaker in that has a higher capacity to handle the load and slowed down the blinkers since LED's have such a lower resistance
you swapped the rears for LED's, well, now here is the kicker, the LED's may be drawing just enough from the car's system to kick that new flasher on and off, you turn on the headlights, it draws more power, not enough amps to push through the breaker to get it to trip, that is what i was originally trying to get at.
so now you have 2 really low resistance sets, front and rear. there isn't enough amperage to heat up the breaker in the flasher to get it to trip with the headlights on.
you may be able to get this to repeat via another method if i'm correct:
keep the blinkers on, leave the headlights off, kick the AC on full blast, stereo as loud as tolerable. you may even need to wait for the cooling fan to kick on as well.
if any of that causes the blinkers to stop blinking.. i'd suggest going back to the flasher and finding something else midway between the old flasher and that new one.
or if you're feeling adventurous, you could go back and throw the old flasher back in and wire in (i'd have to do the math) a resistor on the ground side of the circuits for those, however, finding a mid point flasher may be the safest bet still

If any of these problems started when you installed the LEDs in the taillights (3157 type), it's because the order of the wiring in the Sunfire taillight socket is different than standard 3157 taillight sockets & WON'T work an LED like a standard bulb.....it will either short out or backfeed through another circuit in the car.
Recently, some LED manufacturers have become aware of this problem & are releasing 3157 style taillight bulbs SPECIFICALLY for cars like Sunfire, Cavalier, etc, with these taillight sockets. This is one example of a new product designed for these taillight sockets.......

I Installed Black LED Tails on my 2000 and Used LED bulbs for the rear and I I had a similiar problem with them flashing very faast. Although I did not buy a new blinker I actually went to AutoZone and they offer and kit there that come with 2 resister and I just wired them in and they blink just fine. I am not sure if this would fix your problem but I would feel pretty confident that it will.

Alexis: Dustin, you're ghey, lol. I am better. I have tits, and tits rule all.
Her LED's ARE working, there isn't a problem with the LED's. It's the amperage draw for the LED's thats the problem.
Either they're blinking too fast with the stock flasher, the bi-metal strip inside can't handle that much extra current draw
OR
They're not blinking at all, the new flasher doesn't have enough current to cause it to flash.
Nikki, put 2 LED's in the left side, put the standard bulbs in the right side, use the stock flasher, then switch to the new flasher
tell us what happens with each
pretty pretty please!!

I will try and find the stock one when i get home i don't know if i kept it ...lol (again the new flasher is an electronic ep27 led flasher)
But they are working fine without the headlights on (with the leds and new flasher) the problem is when i have anything my headlights on they don't flash
you need a LED flasher from Grote. Napa can get it.
I don't know why I didn't tell you this before, hahah.
ok i thought i had it fixed i switched the fronts back to a filament bulb...put in my clear outers and then bought the new socket that fried (the grease dried up and burnt lol ) put in my Red LED's
BUT
i got pulled over this morning because the back right signal doesn't work when i have my headlights on...the left one does (both front and back) and the front right one just not that back one
i tested it with my headlights off and it works fine...WTF!
I'm so frustrated lol
p.s. didn't get a ticket or anything which was nice
i Do have a EP27 LED flasher installed
Instead of LEDs, you should just get some
chrome red bulbs (they are chrome when unlit, but still light up red so you stay legal). I have chrome amber bulbs in the front and rear turn signals on the Vibe and I couldn't be happier with them. You get the clean look without having all the issues of LEDs. Than you could get chrome amber bulbs for the turn signals up front. Just my $.02 though

Also, you need to update your Car Domain page because I want to see all the stuff you've done to the 'fire lately

if you MUST have LED's, get them from here http://www.superbrightleds.com/.
I have them in my inner and turns and side markers, and am about to put them in my tail lights, and have NO issues at all.
I'm running the following with an EP27 flasher, no load resistors, and no issues except I had to repin the tail light sockets and flip one of the grounds on the bulb itself since it doesn't have that new-fangled setup as in the link in Sick 99 GT's post

http://www.v-leds.com/Exterior-LED/Turn-Signal-LED/Amber-LED/V-LEDS-AMBER-92-SACK-p7472047.html <-- similar, the exact bulb I have is discontinued and isn't Toyota specific.

To me, the issue sounds like a bad flasher, or power and grounds are crossed in at least one bulb. Multimeter the socket and make sure it matches up to the bulb pins. Use your car's battery to check the power and ground on the bulb. Get some fingernail polish, or 2 sharpies of different color, and use one color for 12v+ dim positive and a second color for 12v+ bright positive, unless the bulbs are pre-marked (most aren't) The blank pins will be ground.

Not sure you know what you mean, LED's have a lower amperage draw than incandescent and the flasher is electronic, meaning it doesn't rely on current draw to trip.
The fronts I have are standard 3157's and were drop in, aside from being polarity specific, bought them in winter 2005. Honestly, I don't know how they ended up working fine. I was using a load resistor for a time, but have since removed them when I went LED all around.
Perhaps because the bulbs are older, they don't have the same type of circuitry as newer bulbs do? didn't do any special tricks
To answer your load resistor question from that post: 50w, 6 ohm is the standard.
Here's the clearest pic I have at the moment... I think they are 24 LED towers (might be 18 LED) with SMT LED's that have the little acrylic domes over each diode.
(edit: and these aren't that dim, I tweaked the exposure some to prevent wash out)

Hmm, I wonder if that company's LED would work better?
Seems to me that a older design will work better. I bought these in 2009, so they are new.
Could you direct me as to where you bought yours?

All my bulbs came from V-LEDs. Shipper is local for me, so I get them in 2 days w/ no extra shipping cost, just wish I could do pick-up since I work near where they ship from
I'll get a newer design and see if it could be the circuitry that is toying with the brightness. These don't do so well during the day time anyhow.
Please let me know on this, it would be a great help.

I have those on the back but in red, you'll love them. I would like to see how yours will work up front, with the LED sides. Depending how it works, this will tell me a lot.

Finally got around to ordering them and they came in today.... no noticeable difference in brightness side to side on both my 97 and 04, both sides work properly as turn signals as well...... tested with and without a bulb in the side marker position.
Maybe you got a bad bulb?
I see the one that you ordered are not the same as mine, I have the (low power) swtichbacks for the front and from the looks of it, your new one is a (high power) 7w bulb. My theory is my low power SB is not enough to send power to the side marker, just because of the resistance that bulb has. I have a feeling if I were to put those same amber 7w bulb in the front, it would work too. It is all about trying it out.
Thanks for letting me know how they worked.
