I can't address the voltage question but I can tell you that when the bulb goes you will be able to see it. Mine showed distinct burned marks inside the bulb. In my case I did not have any yellow blinking lights. My TV did blink the red power light which my manual indicated was a bad bulb.

buy a new unit. for the price of these new if you have a few of the LEDS go out you should just buy a new unit. they are not worth messing with. I have 3 lamps go out on mine after a few hours. they sent me a new one.

That happens because a bulb is out or a wire is bad. This is for if you replace the factory style bulb with an led bulb. The lower watt led makes your vehicle assume the bulb is bad.

I have the same problem with the florescent bulb in the magnifying lamp I purchased from HD. The very first time I tunred it on it blew. Not sure if it's the ballast or the bub but a replacement t5 6400 K 210V 22W is impossible to locate. That's why I'm here shopping for a LED magnifying lamp, lol.

This is suspect. I would check your volt meter....put a load on the relay and measure it again...its a standard relay and there should be no voltage present. I have encountered mystery power from leads before...but I think its just erronious readings from the meter....are you using a good quality meter? Fluke? Klein? Can you hook a miniature light bulb or LED up to the relay leads and see if there is enough power to activate the bulb? Also how much voltage are you using to power the beam sensor? I used a 12 volt dc power supply with great results. One last thing. Connect your switching device and measure the voltage again. My bet is its gone.... This is suspect.

If it's a burnt out bulb...I'm thinking the bulb just needs to be replaced. If something goes wrong with the lamp fixture/ wiring then assume repair or replacement of unit would be required.

On my unit the green light went out after a while, while the unit was still in warranty. The unit otherwise appeared OK. I called Intermatic and after some discussion and email they sent me a new unit. Their thought was that the light burned out. I took the 'bad' one apart and it looked OK on the inside, so it likely was a bad bulb. The green light should always be on when the unit is powered.

Mine does this but the yellow light is blinking. Don't know why but unplugging it and plugging it back in fixes it... until the next time. :-/

I have a 5 bulb fixture hanging over my kitchen table. A high pitched whine comes from one socket. At first I thought it was the socket. I changed bulbs. Same noise. So it's a bad socket, not a noisy bulb. Changed the socket, noise gone.

One of the 7 blue lights is always on, depending on the last setting. Four of the 7 lights are burned out on my toaster. Perhaps this is the reason?

Mine has lasted 2 years now. When you installed it you did not touch the lamp at all with your fingers and transfer anything to the lamp face? That maybe could create a hot spot and it burned out? Sometimes there is just a defect.When I first installed it I must have jarred the optical block so I had a rose tint across the top of the screen about 3 inches down. After a while you learn to ignore it, but I noticed recently that the line is gone. I moved the set a bit recently to get at a side connector and I am wondering whether that jarred something back in place. Now I won't move the set at all until the bulb dies again or something else goes south. Mine has lasted 2 years now.

Typically when a fluorescent ballast is failing you will see the light flickering then eventually it goes out. There are two plastic clips that hold this ballast in place and pins on the ballast that plug in so if one of those clips is broken the ballast could be hanging and not making good connection on the pins (the clips broke on mine that I had to replace). There could also be a component overheating in the ballast causing it to turn off.The short of it really is if you've replaced the bulb and you know the switch and connections are good then there isn't much left other than the ballast.

That is the symptom I had that caused me to buy this bulb.Installed it and have been good every since then. Call the seller and see what they say.

Hi Judy...i can't explain why it flickers. Mine flickered - or I should say the light screwed into it - in the twilight period before sunrise and sunset. Once it became totally dark or light, the flickering would stop. If your flickering continues during complete light or darkness then something is wrong with the unit if you had no problem with a standard bulb. I switched to an LED bulb with a built in dusk to dawn sensor and have not had any flickering issue.

Does it blink green then go away totally and then the red light stays on or just no light period, and is there sound during this ? Because I changed one out and it blinked as you say then went to red and was defective bulb. So I sent it back for a replacement. Another time I replaced one and it did something similar and I think it wasnt making a good connection so I took the bulb out and used attachment to vaccum out all the dust that had accumulated back there and re-installed bulb and it worked great.

So, mine has started doing the same thing. It has been months since I replaced mine and it is just now flickering. My guess is that the bulb is just cheaply made and not a true Factory bulb. For as cheap as the bulb was I wouldn't expect much over a year out of it but the flickering is pretty annoying. I don't know of a fix other than getting a new bulb.
