So can someone make this clear what we need to do the switch backs and how they are installed ? Do you just switch out the front stock bulbs with the LED one?
Edit, apparently its plug in play, but how would this work with 04 sedn tht has the amber corners. Would it still output white?
Yes, it's plug n play, just replace the lamps with the new one. It does have an amber reflector that will always be amber until you remove the housing, bake it to remove the lens and pry off the amber reflector. Honestly, if your not much of a DIY'r then just leave it in there bro.
It's a much cleaner look IMHO to have all white up front, it will still be white in your parking light chamber because there is no color in that reflector, just that little 1x4 piece on the side of each headlight housing.
Keep in mind, you MAY need a resistor, all that is is a piece of hardware that goes in between the wire to your light bulb socket. Again, if your not a DIY'r you could try this and see if you can get away without a hyperflash (flashing fast like a bulb went out) I beieve I read that someone changed one set (front or back) to led w/o a problem. It wasn't until he dis the other side (front or back) that he came up with the hyperflash.
