Why are my LED high beams not working?
By far the most common reason your brights will stop working is from a blown fuse or a bad relay. Or, it could be a bad relay. If the headlight relay has failed, it may not respond when you attempt to switch the high beams on. Replacing the relay should restore the system and get your high beams working once again.
Why are my new LED headlights not bright?
LEDs are sensitive to several things that you need to be careful about. LED bulbs can lose their brightness due to premature aging, bad internal components like a capacitor or LED arrays, or the common cause of loose wiring. Heavy load appliances on the circuit can also cause that LED lights are dim.
Why my headlights are not bright?
The most common reasons why headlights don’t get bright enough are that they either a lack of voltage in the circuit, the wrong size bulb, or the lens of the headlight is oxidized or faded. If that is fine then the lens on the headlamp may be faulty. These things would need to be checked.
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.
Do you need to plug in low beam bulbs?
Although this is not needed, it will make installing the new low beams a little easier. The low beam and high beam bulbs have these little tabs that need to be pressed in and twisted (locked) into place. These plastic tabs are pretty awkward to plug and twist into place if you have a tight space to work with.
Is it easy to switch LED bulbs into factory light assemblies?
Yes, switching LED bulbs into your factory light assemblies is easy. However, if you’re interested in seeing some stylish custom-design lighting assemblies that also include LEDs, we invite you to read our related articles which take a more in-depth look at LED headlight assemblies, headlight conversion bulbs, tail lights, and underbody lights.
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.
