My headlights were already upgraded to LED prior to purchase. I just changed the fender front marker lights to LED and the difference is awesome. Now the fog lights look yellow and dull. If they work better or even the same that is alright. I'm most concerned about being seen in day and in dark. Has anyone upgraded the BRP fog lamps to LED's? Without taking skins off... not sure of bulb size. I think it is an H8. Thanks for the help, people. This is the go-to site for anything and everything Spyder! (2010 RS)
