I just swapped my 88 crx tail lights out for 91 crx tail lights. When I did the swap I had to swap the wiring harness too.

After the install I have one tail light that is dimmer then the other, what could cause that?

 

bulbs about to burn out. or you have oil, silicone on it. just replace the bulb. if it is still dim. then it may be the harness itself.

 

Thanks I will replace the bulb. The harness is the same one my cad had before, so its not the harness.

 

Ok changed the bulb, and checked all my fuse's and they are fine.

BUMP WHAT THE HELL IS WRONG? STILL DIM!

 

jiggle the plugs, could have a bad connection.

also, look inside the light to make sure theres not a residue inside there

 

I don't think its a bad connection, and there was some water in the light. Would that do anything?

 

check your grounds
