Well wouldn't you know it ..... I recently purchased a new front sidemarker for my 06 TL because I assumed that the LEDs were going bad because they were very dim..... So now when I plugged in my new LED sidemarker it's still dimmer that the rest !..... What could be my problem ??? HELP.....

 

it's gotta be a voltage issue going to THAT particular sidemarker. trace the wire back to it's source and make sure no splices or breaks in the wiring!

You original owner?

 

Wow sorry about the late reply...... Been busy with snow .... Lol .... Yea I'm the original owner ...... And it's funny I thought by buying a new light it would work but still it's dimmer than the others......

 

It also might mean you have a ground issue on that one light.

 

Try using a multimeter to check the voltage
