I found some Series 7 clear rectangular shaped side markers at Pep Boys, part #40255277. They came with some wild LED multi color lights that I removed. I picked up pre-wired side light bulb holders & bulbs for a Jetta at the local VW dealer and they slide right into the Pep Boys side markers with a little modification. I did have to open up the holes under the badge somewhat for the light to slide in to the body. I wired up the side lights per the CEG sidelight wire guide and it works great. The sidelights come on dim when the parking lights are on then blink bright when the blinkers are turned on.
