The clearance lights were leaking and the more I looked at them the more I didn't like them. My van is a 159 HT, with only 1,000 miles. So I went looking for a suitable replacement and went with the smoked teardrop with sealed 9-LEDs lamps. The PM light is 3-1/2" center to center, new light 3" CtC. Didn't want to drill the van body. So the mod was to drill a new hole in the new light base 1/2" further back. I also got some thicker 1/4" foam sticky back weather sealant gasket to use on bottom of light and reused the bottom gasket under to lens. This heavier gasket allows the light to flex a little when mounting and stay sealed. The wiring was very easy, cut the old light off and new lights have a plug, cut that off and butt splice connection. Use the clip on a pen to keep the wires from dropping into the van. I'm liking the look.
