Some of the leds have gone out what could of caused this?
a rock could have been kicked up into it and broke it.
should be super cheap to replace, as long as the tubes can be dismantled.
If you put it too close to the exhaust they could have melted wires or the lights themselves
vibration/poor soldering would be my guess.

car audio noob since 1984.
poor sealing and water or condensation blew my leds
set the example, never let the example set you.
Thanks for the information
