I put some hyper white LED bulbs that have 6 LED's in them in the parking lights, the one's up in the front corner of the head lights. I also put some in the clear side marker lights, they were called inverted cone type, they don't shine straight out they kind of shine to the sides. They have a blue tint to them and really look good on an Aero Blue car, but now the light on the dash is on that tells you that you have a light out. The sensor for this dash light must work off current draw, I've got some 9 light LED's ordered to replace the 6 Led one's in the parking lights, the 6 one's are not as bright as I wanted. I hope the 9 Led one's pull more current and will make the light on the dash go out or I'll be looking for a fuse. I also put a pair in the dome light, they look pretty cool with that blue tint to them shining on the upper console with all the CTD surrounds that I have.
