Headlights: switchRecall 00V-174 · Thomas vehicles

The problem

CERTAIN SCHOOL BUSES WITH WELDON TECHNOLOGIES' 5050-1400 SURFACE MOUNT MARKER LIGHTS HAVE AN OPTION TO REPLACE EACH OF THE TWELVE CLEARANCE/MARKER/IDENTIFICATION LIGHTS WITH FOUR-CANDLEPOWER LIGHTS, TWICE THE CANDLEPOWER NORMALLY USED. THE HIGHER CURRENT DEMAND CREATED BY THESE LIGHTS CAN CAUSE EXCESSIVE HEAT THROUGH THE HEADLIGHT SWITCH CONNECTION IF A RELAY IS NOT INSTALLED BETWEEN THE COMBINATION TAIL/MARKER LIGHT CIRCUIT AND THE HEADLIGHT SWITCH.

The risk

THIS CAN RESULT IN DEFORMATION OF THE PLASTIC CONNECTORS THAT CONNECT THE HEADLIGHT SWITCH TO ITS WIRING HARNESS.

The fix

DEALERS WILL INSTALL A RELAY TO REDUCE THE CURRENT DRAW THROUGH THE HEADLIGHT SWITCH. OWNER NOTIFICATION BEGAN SEPTEMBER 8, 2000. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT THOMAS BUILT AT 1-336-881-7219.

ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S AUTO SAFETY HOTLINE AT 1-888-DASH-2-DOT (1-888-327-4236).
