They are polarized so they can go in backward and not function properly

Worked great and since the leds are only on one side i was able to point them down in a floor courtesy light which reduced the light in my eyes

These red leds are great looking in my vehicle for actual light output and trying to see a map its probably not the best option

Cool green dome light but only work when doors open or you turn the switch on map light in dome light dont work

Only problem is they stay dimly lit after you shut your door or turn your interior lights off by switch

I had to use a file on every light i got and file down the circuit board that is on either side of the round metal connector on the ends

You can see where it should be cut as there is a printed line on the circuit board

Since it is cut slightly very slighty outside of that line and not on it none of the lights would light up when i put them in because the circuit board was connecting and not the round metal end piece
