The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2001-2003 models is #4114K (trade number).

The first one that burned out on the truck - running light. I bought this truck new and this is the first bulb to burn out. I know none have been replaced before. The one that came out was a 4157K. The book says 4114?
