This may sound a little biased because I have some, but the colored ones don't look good IMO. K' this is my thinking. The white(pure white ones that is, not the bluish white) and especially orange ones, actually serve a purpose, even more if they blink w/the blinker. They add a little more visibility, kinda like signals on the side mirrors. I would first look up the laws and regulation for your specific area and then you will have a better idea of what to do, ie: putting them on a switch or wiring up the the parking lights. Don't let people bug you about them being rice because you know what. A friend w/ an svt and I put them on our cars and now the majority of the OK crowd I know has them on their tours/cougar (all white led's btw) oh yes, and if you wire them up to the parking lights you just wire the white led wire into the orange wire on the parking lights and ground the black wire to the frame or the black wire on the parking lights. To blink w/ the signal, the white wire still goes to the orange one on the signal, but the black now is spliced into the blue wire w/orange strip, instead of being grounded. Have fun.
