The dash switch for the clearance lights passes a lot of power for the clearance lights. My markers are not working because the blink clearance lights switch burned up.

I will look for the switches I removed and let you know. Did this switch have the lighted background and lettering on it?

Check this one:http://www.amazon.com/dp/B0031OVARY/ref=asc_df_B0031OVARY2337320?smid=ATVPDKIKX0DER&tag=dealt5041-20&linkCode=asn&creative=395093&creativeASIN=B0031OVARY, and then if you needothers call Mouser Electronics Inc. with dimensions and function and if it exists they have it. www.mouser.com
I found that if I can get a new switch I get new technology (better alloys in the actual connectors inside the switch and better housings.) I try never to use old technology unless I just can't find a replacement. Mouser has had every switch I needed for my revised dash and the convenience switches throughout the coach.
