Last night I installed the 91 solid red tail lights on my 89 LX. I plugged the lights into the factory wiring harness after I compared the old with the new. They seem to be working fine from the outside of the car. The only problem I ran into is that the dash light "Rear" comes on everytime I press the brakes. I know its suppposed to mean a bad bulb but I used new bulbs and they work. I looked in my 89 Dealer service book and I can't get a clear answer out of it. What do I have to do to make this installation correct?
