Why are there two fuses for high and low beams?

Why are there two fuses for high and low beams?

According to the electronic manual (not the owners manual), the same fuse is used for high and low beams. The reason for two fuses is one is for left and one is for right. There are also two headlight relays (left and right) but they do not control the switching of low or high beams either (same story as the fuses).

What to do if your high beam light is not working?

Check your owner’s manual to be sure which kind of high beam bulb you need and get familiar with the fuse box in case the high beams stop working. Finally, practice using a digital multimeter so you can rule out electrical problems before replacing other components. A blown high beam headlight bulb, an easy fix.

Can a blown fuse be switched back on?

The breakers reset and can be “switched back on”–so there is no need to replace anything. Much of the time, it’s technically inaccurate to refer to a “blown fuse,” so in this article, we’ll offer you some new concepts and vocabulary to describe your various electrical concerns.

How does a high beam light bulb work?

Get familiar with the fuses and relays that control your headlights. The headlight switch usually doesn’t control the headlight bulbs directly, but through one or more relays. The headlight switch powers a relay, which powers the headlight bulb. This protects the headlight switch from the high current used by the high beam headlights.

Do you need to replace high beam light bulbs?

Other headlight systems use two halogen bulbs in each headlamp — one for high beam and one for low. None of them will need to be frequently replaced, but they won’t last forever either. Some experts recommend replacing all headlight bulbs or filaments at the first sign of failure, particularly if they are original equipment.
