i bought some LED lights for my TL interior n i try installing them on the back seat dome but they didn't work..Can somebody help or give advice???

 

search the forum, im sure there is already a post on this subject. Google the problem and put acurazine and your car model and year after the description of the problem and it should pop up with several links that should be helpful.

 

LED bulbs are polarity sensitive, meaning, if plugged and and it doesn't work, go ahead and flip the leads and plug in and it should work. If it still doesn't work, chances are the bulb is defective. Flipping usually does the trick though!
