How to Test for a Faulty Light Bulb

[@carlford5287]

Thank you for posting this video. I appreciate the short and to the point instructions

[@4DIYers]

You're very welcome and thank you for the kind words!

[@FrankBenlin]

Wow, someone with a check mark that actually answers viewers questions. Good job, thanks.

[@4DIYers]

Thank you so much! I try my best to get to all the questions asked.

[@silvanaribeiro8168]

This video is good only if you already know how to use a multimeter which is not my case. It would be to have an explanation of how to set up and turn the multimeter on.

[@AndyNav1]

Thanks for the video. The single filament bulb I have, doesn't light up on the car. When I took it out, noticed the glass has some black sooth on it, however, there is continuity. What is your diagnosis for this bulb please. Thanks.

[@4DIYers]

Black sooth sounds like it’s burnt out.

The resistance readings that I get from my headlight are not in line with the manufacturer specs and don't even compute with my amperage readings (about 4.7 A at 14V) according to Ohm's Law. Any idea what I am missing? Thanks again for the tutorial.

[@Solutionist1]

Concise, clear video. Cheers mate

[@4DIYers]

Thank you!

[@keithfernandes183]

Nice. straight to the point.

[@4DIYers]

Thank you!

hi, my bulb low beam is not working, but the high beam is working fine. I want to know how where to put the multi meter connectors to check each low and high beam thank you Tony

[@cooldude2245]

I have a car lightbulb that filament intact, so I tested continuity and no. Only think I think is the lead? Pointy part wore out?

[@chrisorourke3363]

How do you test a halogen tube type bulb all by itself? The kind that sorta look like a neon tube. Thanks for posting this helpful video.

[@davidm3210]

To make sure that your m.m. is functioning, it's advisable to touch the leads together to check them for continuity before you begin. Also, I like to use the diode setting for the audible beep. Cheers!

[@Alrashdi]

As you did in the first bulb, you said that it's not working and should be replaced. Once I did the same thing with mine by the multimeter and it shows no signal but when I plug it to a battery it works! why is that? I'm sure that I put the multemeter on 200 ohm! What do you think?

[@4DIYers]

+‫حامد الناصر‬‎ The filament could be broken, but when you apply voltage it reconnects. It's most likely on it's way out.

[@jasonwight7726]

thanks for the video. I have this multimeter and now how to test my bulb.

[@4DIYers]

Glad to help out :)

[@KnowingGodExplorers]

Would be nice if you show where to set the multimeter to instead of just telling people every multimeter is different especially for beginners

[@Ion1cBomber]

If you paid more attention you would see that the multimeter is set right in front you . Maybe you want him to explain , but it right in front of your face . Just saying .

[@rpmzzz]

How do you test a H3 bulb? I have it set to BEEP if there's continuity

[@fvg3401]

question! getting an aircraft light blub to work off 12 volts that require 28 volts? Is there an easy fix? It's a small bulb like in your video here. Here's the info on the back of the bulb (Micro lamps ML- Cage code 61951 M6363/2-2 28.0 Volts. Thanks

[@Parymary-ix5db]

Very Useful 👍

[@zaidmemon8495]

Hi, i changed brake light bulb but whne i press brake pedal, the tail light bulb glows with high power instead of glowing brake light bulb. Can you suggest what could have gone wrong..??

[@4DIYers]

I saw the video you posted. There maybe a wiring issue or could have been the wrong bulbs, either before or now. I know some European vehicles have a two stage brake lights, when they're pressed normally they illuminate as they should and for hard braking, they activate another circuit for brighter lights.

[@whatstheproblem6606]

Prolly your bulb installed wrong

[@michaelcordero5588]

What's the setting on ohms? 20k, 200?

[@awfullawton4470]

200

[@brianpacheco1927]

Hey man I got one of those really skinny halogen bulbs I don't know where the connection is (I don't see any copper or metal) where should I test it? Do I need to take the socket out as well?

[@4DIYers]

Yes you will need to remove the bulb from the socket. Don't forget to subscribe!

[@brianpacheco1927]

So my socket is only reading 0.1V at the 200volt setting on multimeter. Doesn't seem right because it should be reading 12V. Any other tests to rule out the wires and just be the socket?

[@billwilson5341]

Brian Pacheco: Wish there was an answer ...

[@Thetrucky69]

Excellent information.

[@4DIYers]

+Thetrucky69 Thank you.

[@Thetrucky69]

+4DIYers No probs mate cheers.

[@addie7846]

Thanks much

[@4DIYers]

You're welcome!

[@GodsHerosGodsHeros]

Brilliant

[@ledmk2]

Nice video

[@4DIYers]

Thank you!

[@MRFORD21]

Thank you

[@PBS-nm1uu]

thanks great info, i am wiser thanks to you .

[@4DIYers]

Thank you :)

[@marilynilagan482]

where to set the multimeter

[@4DIYers]

+Marilyn Ilagan To the lowest Ohms setting.

[@homerpreyer1496]

Thinks on helping me lern how to check the car light

[@Ebolson1019]

What about the socket

[@4DIYers]

+Bryan Olson I'll see what I can do for producing a video on that.
