Hello all. I have an 04 Camry SE and I'm having a problem I've never seen before. I replaced both factory headlight assemblies about 2 weeks ago with a halo projector assembly I purchased off eBay. The install went well and didn't experience any unusual problems, but about 3 days later the check engine light came on. We took the car to the dealership and the identified a problem with the transmission sensor. They "fixed" it and we picked the car up, only to have the CEL come on again about 10 miles up the road. Long story short, we did this about 3 times...the last time the dealer said they were unable to identify a problem and just reset the light.
Now while driving with the headlights on, if I press my brake the right turn signal and reverse lamp light up on the gauge console until I release the brake pedal. If I signal to turn right the right blinker blinks very fast (although the bulbs are all functioning), but when I signal a left turn it blinks normally. The other thing is the rear turn signals don't blink the same when the headlights are on. When I signal left all is normal, but when I signal right turns the brake lights and turn signals alternate blinking between one another. But it only happens with the headlights on.
I know this is really weird, but any help on this would be great.
