Will not shut off at all ? Weird ! The only minor issue I have is the slight bluish tint the LED"s throw off other then that all 100% off
Going to replace the headlight bulbs soon as weather warms and polish the lens covers as they are hazy !

 

No here is a night shot

This is thru the driver’s window, dome lights on.

 

WOW mine shut off lust like the regular bulbs did ! Yours must be getting some feedback !
I am curious can you reverse the wires ?
so any difference ?
I know mine would not light id I had polarity wrong !

 

No, I tried reversing the bulb, then they just don’t light up. I just got replacement festoons from Amazon, 3 minutes to change all seven in my 2011, they all light up very bright and the centre bulbs dim and turn completely off after you close the doors. Fixed! But they aren’t as bright as the square ones, I might rig those either in the foot wells in a manual switch or as under hood lights.

 

I guess those square must be real sensitive to back feeding ! I do like the LED'S better then regular bulbs !
I have the Under Hood light in the engine bay of my truck and went to LED as well, A nice feature,I have been thinking of adding under hood to the HHR as well.....:)
Next thing the HHR is getting is KROWN Spray. My truck goes in Monday and the HHR next week. Best part I do not get dirty doing it lol

 

Soon, I will be changing all interior bulbs to LED. Does anyone know have many bulbs are required in each fixture?
