Description
Truck-Lite Model 26 incandescent yellow beehive cab marker / clearance light, a direct replacement for Signal-Stat SS1340A and King Diamond KD5163101 on heavy-duty Class 8 trucks. 12V hardwired with stripped-end and ring-terminal pigtails, chrome-plated plastic housing, 2-screw mount with rubber sealing pad — drops into the OEM beehive marker position on Peterbilt, Kenworth, Freightliner and similar Class 8 cab rooflines.
Signs You Need a New Marker Light
- Marker / clearance light fails to illuminate with running lights on
- Yellow lens is cracked, faded, or shows moisture inside the housing
- Bulb has burned out repeatedly — usually a sign of a damaged socket or harness
- Mounting pad has dried out, allowing water to enter the cab roof
