Headlight Bulb Testing: Fuse | Relay | Electrical Controls | EASY FIX
#headlight #bulbreplacement #autorepair
In this video I show you how to test a headlight bulb at home.
This includes testing the headlight bulb itself (visual inspection, in car, and on the bench), testing the circuit fuse, testing the circuit relay, and all other electrical components associated. This can be an easy fix once you watch this video!

Thanks for taking the time to make this video 🍻
Anthony, I just want to say thank you my Tacoma is having this issue on the low beam. I can’t wait to get home and do all the test and see if it’s a bulb or a relay. Thank you so much.
Very helpful video. I was able to locate the problem to a bad fuse. Thanks.
Great video!! Short & concise!! Thank you for sharing this.
Thank you so much sir it's really helpful for me .....I'm also a automotive electrical student from
Great video! You explained it very well. Thank you very much.
Great explanations!
That's cool man I knew nothing thanks to youtube I am the wiser. I like how you tested thing harness and fuses, the relay would be a big help, also need the tools, but I have friends 👍...I didn't know you had to readjust the lights after installing them...the main reason I was trying to reach and see if I can get the bulbs in without the assembly removal was part of that, also that is what my manual states on doing, but even then your put the light back to its fitted position which shouldn't be much different. I watched vids with the dot point homemaid board for height distance, driver side 4" below the dot measure 2" on the passenger....so ya, I was surprised to hear you recomend adjusting them always. Thanks great for someone who never had prior knowledge...they want 200$ plus to mess with this simplicity. Video on the wiring harness both ends would be cool. I have a question, what if 1 low beams working, to separate lights not like your luxury one that you got here LOL, you put a bulb in the running light works but the low beam doesn't what does that mean?
I have a 2002 Chev tracker,my light bulbs are tested and good,problem is my left light is almost amber while the right one is bright and clear. Ever come across this problem before? Great video,thanks
My daylight running lights are out, so I switched out the fuses. Still no DRL. Now however, my driver side headlight is out. I replaced the same bulb months ago. That specific headlight was always running brighter than the other. Both hi beams work when I put them on
Great video!!
Thank you very much
This help but i still need a little but of help…so my low beam bulbs dont work on both sides but the lights on the side of my headlights work…what does that mean?
