i just picked myself up a 2003 wrx, it has a sti spoiler fitted but unsure if its genuine or not, but the LED brake light doesnt work properly, come leds work and some dont. is it possible to buy these led units and just undo the 2 screws holding it in, unplug and fit a new unit? the light fits in the spoiler on the part that sits on the boot, not the very high level one that sits on the top part of the spoiler.... if that makes sence?

 

I'm pritty sure you can buy them off eBay. I was looking at the the other day. Will try and find the link for you buddy
