Ok so I didn't realize this untill now but it seems like when my lights are off and I press down on my brake, my gauge lights turn on. I'm not sure if my lights are supposed to be on at all times or not because I can't tell because my gauge lights are super dim (still using stock bulbs). So when driving in the day time I cant tell if the lights or off or not.

Also, I think somethings off with my cluster, whenever I go over hard bumps my lights flicker. I think I either need to check something or sodder something. I'm not sure.

Where should I start to look?

Yea, my cousin just told me that my tail lights flicker too.

When you say take them out, you mean unhook and rehook them?

Sounds like a lose main ground or a short. Put a volt meatier on ur dash harness at the ecu and see if you have any low/high spikes. If not do the same thing driving around with a friend testing it for you. If you can find the wire that is spiking you can folow it back to see what the problem is.


Good luck! Let us know what you find out.
