Joey Mack Posted Monday at 08:04 AM Share Posted Monday at 08:04 AM Are you talking about the flash to pass light switch at the top left dash ?

Geoff Weeks Posted Tuesday at 05:11 PM Share Posted Tuesday at 05:11 PM (edited) Somewhere I have a Cole Hersee book that has the switch and the wiring for that. IIRC it had 3 positions, center was off. Found it! (not in current Cole Hersee catalog) Sw number 55071 Had 3 terminals on the rear, Battery, Marker light feed, and common out to the marker lights. Flashed on for daylight, off for night time, by moveing the switch in opposite directions, spring loaded to center (normal) position. Cole Hersee's version worked with lights on or off.

h67st Posted Tuesday at 06:33 PM Share Posted Tuesday at 06:33 PM There's one on ebay for $18 from Arkansas Valley Diesel (their customer service is a little spotty, so hopefully no trouble getting the switch). https://www.ebay.com/itm/156308028277?_skw=cole+55071+switch&itmmeta=01JJ5201GZ2WZ44X84GZ1YC356&hash=item2464af3b75:g:z1oAAOSwWi9hRQP0&itmprp=enc%3AAQAJAAAA8HoV3kP08IDx%2BKZ9MfhVJKlAl%2By20gw3p%2BH6DLgI93FaVwVagQQ9Joh%2BsYhsMJuSmVCPayt8ZinO1Wx9o4ZuZhzjbXVAiaNfJYfzKtjM0mC4%2BCDSSRzbKMALUyX52FN1TjMvE4ydtu65%2F1S9ZY%2FxUIzvbEmSPQsLMxDdz6wGDQwnMVL1uQYSi9W%2BMf2jLzv4VbvIBp3QjGf4P304FCPqDi%2Fa0FVkQj%2FbmeRTDAmRjtaSi%2FWw6vUIRy8BxnRVuNQeaImwXQY92SnB1Fu9o9gHFY0i4VSG%2Bdu0xVG8PnhCTn88Dh3foNmH6CqdLaLmY9HMTw%3D%3D|tkp%3ABk9SR9SYgKKRZQ 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75029-clearance-lights-not-working/#findComment-567158 Share on other sites More sharing options...
Geoff Weeks Posted Tuesday at 06:57 PM Share Posted Tuesday at 06:57 PM I have successful bought from them in the past, but prices are high, and would not be my 1st "go to" place, They do seam to have some of the more "odd ball" parts.

Joey Mack Posted Tuesday at 07:23 PM Share Posted Tuesday at 07:23 PM Take a look at the 2 stud rails on the firewall by the steering column. You may find an in-line fuse there, and possibly the wire broke off the post. Its a short distance, so tracing the wire to the switch may be easy.
