POV LED Light Issue

[nyyanx18]

I have a Blue Signal Mini Phantom LED light that I use in my personal vehicle as a deck light in the rear. Lately, it has not been working all the time, especially when the car is very cold. Sometimes, I'll switch it on and see only a quick flash, then nothing. I used to use it in the windshield until I upgraded to a bigger light and noticed the same problem. If I smack it a few times, it comes back on. Obviously this is not a practical solution, especially with it being in the rear of the car. It seems that once the car has been on for a while and thoroughly warmed, it works fine.
Is this just a loose connection somewhere inside the light that is made worse by the cold?
The light is probably about 4 years old now. I recently got the light wired to work with a switch I have for other lights (used to just be cigarette plug, but issue was happening before the switch).

Are you in NY? Anywhere near Avon? Take it to the factory, they have a repair shop there.

I'm in NJ. Google maps says about 320 miles away.

Not to be smart - UPS?

Shipping+repair costs would probably come out to be more than just buying a new one.

Open it up and see if anything looks broken/out of place. Loose wire, missing solder, etc etc.

elightbars.org is the place to go for that. They have people who just get the biggest hard on for emergency lights in the entire world.

Shipping to them is under 10 bucks, USPS If it fits it ships.

Anyways, do like Chenzo says, open that sucker up and look around.

If you smack it and it starts working or it works fine when it's warm then you most likely have a loose connection. Open it up and check the solder connections. If you can't find anything, any good electronics repair place can test it to see if a diode went bad or be able to track down a cause.
