What is the 2002 Ford f250 headlight relay location?

The 2002 Ford F-250 headlight relay can be found in the main fuse panel that is under the hood. This is against the firewall on the driver's side of the engine compartment behind the battery. If Your headlights are not working then the first things You should check are the fuses and the relays. These can burn out over time, but if they are fine then there is likely a different problem. The bulbs in Your headlights can burn out over time just like any other lightbulb. You should check those and replace them if You notice that the filaments are damaged in any way. Your headlights may also not work when there is a loose wire.
