LED bulbs will have a different resistance than standard filament bulbs. You may find yourself having a problem with the speed of the flash.

The flasher module is a relay, which relies on the resistance of the bulbs to regulate the flow of current through the electromagnet.

Hmm, i didn't know that. Does this mean there's a chance the light will flash too quickly, sort of like when one of your turn signal bulbs goes out and the others flash quickly to alert you that one is blown?

holy crap, i just received the LED bulbs - that was fast!
No just gotta figure out how to get access to the bulbs. Anyone know?

It depends on whether the LED's were designed to work in the turn signal or not. Most LED bulbs are general purpose and will not be designed to work with flashers. If that is the case, then you would have to get a load resistor. You'll know when you try to use them.
If your 07's access is like the 03-06, then you'll have to pull off the carpet like panel behind the light assembly.

Seems like a dumb thing to leave out, I agree. LED blinkers would fit well on this car

Where did you get the LEDs from? I found a site selling some with the standard bulb bases
http://www.superbrightleds.com/cgi-b...gi?product=CAR

Ive always wanted to change the rear turn signals to LED in my 05 since i got it. I think LED turn signals are pretty SICK looking especially when the tails are already LED.

Cant wait to see the pictures and hear if it worked out.

This is where I got the lights from:

http://www.superbrightleds.com/specs/7443.htm

It's actually the 7440 that the car takes.
I just installed them - extremely easy, took 1-2 minutes each side and no removal of anything.
I put the whites in on the left side and reds on the right side and turned on the hazards. They look awesome - the red looks better because the whites are actually a tiny but blueish pruple like all white LEDs look so when that light goes through the red lens a slightly discolors the light. The reds give a nice deep red output that IMO matches the brake lights better.
I'll post pictures later tonight when I get
home and the conditions are better.

Edit:
Although the hazard lights work fine, the turn signal flashes quickly when signaling left or right. I'm going to see how much that bothers me - if anything i can just change it back to stock.

So the hazards flash normally but when you signal left or right it flashes faster? Thats odd.

I kinda expected this to happen.. blinking too fast

yeah the car senses the low power consumption of the LED bulb and thinks its burnt out, and increases the flashing rate to alert you that your bulb is 'burned out'. A load resistor or a flasher that is LED compatiable will fix that.

That makes sense. How hard is it to install a load resistor and where would I find one?

Here's video of the different light combinations.
I'm new to photobucket, so i only have the links copied to this thread and not the actual video itself. Can someone give me advise on how to do that for next time?

that first video is why LEDs are better, look how much faster it illuminates than the standard bulb. And the white LED is too dim IMO, and as said earlier white LEDs put out a slight blueish tint, they arent totally white, so i think it would be best to stick with red.

Load resistors and LED flashers can be bought on that same site where you bought the LEDs, or ebay. I think the LED flasher would be the way to go but idk if it will work our cars and if it would be compatiable with the standard bulbs in the front of the car (if left standard)..

Looks like you don't need a load resistor. They look just right. Where did you get your bulbs? Also, I agree the red LED's look much better.
