How can you tell if a headlight fuse is blown?

The blown fuse will be obvious since the wire element within must have melted or burned from the higher electrical current that passed through it. You may also use a multimeter to identify the dead fuse without having to pull it out. These tools are affordable and easy to use. Once a fuse is blown, headlight dysfunction will be the resultant effect, this could come in form of dimming lights, high beam working and headlights not, headlights flickering etc.

In case you don’t have access to your handbook, here’s a quick one. For a 55/60-watt headlight bulb, the fuse that goes with such is usually 15 to 20 amps. Nowadays, headlight relay kits are designed to run 100-watt headlight bulbs with 25 to 30-amp fuses which is a bit of an overkill but will increase the life of the fuse.

Manufacturers often use a higher-rated fuse in vehicles, even though headlights don’t have much surge current on startup.

Conclusion

The importance of replacing a blown or burned-out fuse with the right replacement fuse is a game changer. When the wrong fuse is used, this could lead to further issues. The confusion about which fuse is for the headlight will be resolved easily by consulting your manufacturer’s manual.
