Hi,

I just got a 2009 TL SH-AWD TECH and the left signal was flashing real fast, normally that means the bulb is to be changed so i did (front right turn signal just above the fogs), but turns out the copper connectors in the socket were really dirty and pushed too far in the socket, so even the new bulb would not resolve the issue.

Cleaned it out, pulled up the coppers connectors using a copper stick, put it back in and now the turn signal works just fine when activating before a turn BUT i noticed that when the lights are on, that signal light that should be on like the other one does not light on (But again, it works when activating turn signal).

My guess would be to just replace the socket, but dont want to buy one for nothing ... Thank you for you input.

 

check the rear on the same side as well

 

rear works just fine, not sure you get my issue, the front right signal works when signaling but does not light when lights are ON.

 

You may have bought the wrong bulb. Did you get 1157 or 1156? You need an 1157 and I'm guessing you got the 1156 because it only has a single filament. It will still fit in the socket but won't function properly.

If you're not sure just remove the bulb and look at the bottom. It should have two "nubs". One for the constant on when your lights are on and the other is for when signaling. If you remove the other bulb that's working correctly you'll see the two "nubs".

 

I remember seeing 2 nubs, but that would confirm my suspicion that i need to change the socket, maybe only 1 polarity works and that is why i can signal but not get constant electricity flow, will test using the socket from the other side.

Thank you, very informative, will report back with results.

 

Turns out that just cleaning the socket was all i needed, the fact that it didnt work at first is that the new bulb Acura dealer gave me would not function properly for one of its function (even tho it was the right bulb size). Ended up putting back the old bulb and problem solved.
