50 in lightbar flicker

Hello!! So have a 50 in led lightbar on my Jeep. Today as I walked past it in the sunlight, I thought it was on.. But not completely on, more like dimmed and flickering.. It was in the sunlight so I assumed it was just a reflection. But come night fall, I could definitely tell something was wrong. It kept flickering and was dimmed as it looked like it didn't have enough power. I've also got a switch for it that has two small lights red/green for on/off. Usually, when I press the button, red goes to green immediately and turns the light bar on. But now, there's a big delay from switching it on and sometimes there'd be no on/off light at all! And the light bar would flicker, turn on, flicker, and so on.. It wouldn't stay on! I've no idea what's wrong with it. Last I drove my Jeep was last night and everything seemed fine. It's been sitting there in my drive way all night and day, it also rained.. Could the rain mess it up if there's an open wire or something? Any help is appreciated!

The first thing I would do is get a meter and check the wiring coming out of the switch to the lightbar. If the light is somehow on when the switch is off, you may have a bad switch. It doesn't sound like the problem is in the light since there should be no power at all to the light if the switch is off. The problem could be water...but only if your switch is wet. Actually, I guess water could short out the wiring going into the switch if your connections are not well-sealed. Regardless, you should check out the wiring with a meter and make sure your hot wires have the right voltage and your grounds are good. If you don't have a multimeter, pick one up. They are cheap and easy to use.

Your post is a little confusing. I assume you are saying the light is on when the switch is off. If that is not the case and the light just flickers when you turn the switch on, you could have a loose connection.

x2 on the switch. Get a standard toggle switch. A friend of mine bought a set of fog lights that came with a push button switch and the switch was dead right out of the box.

So I checked all my connections, everything seems good! It was a faulty switch. I changed switches and the light bar works! However, it still does a quick flicker every now and then.. I've had the lightbar on for some time and I rechecked the connections to my battery. The wires are warm and getting warmer by the minute.. I can smell the heat. Is that normal for this amount of light output or is this something I should be worried about?

What kind of amps does a light like this draw? Wouldn't it be a really good idea to use a relay & heavier gauge wire on this kind of install?

A 50" bar usually draws 17A+. I'd only run 10g wire to a light that drew that much imho, unless a short run then maybe 12g... I'm sure the wire it came with is undersized which doesn't help. Could be a cheap relay too, what brand bar?

Ridged Ind. Called lady, from ridged, said to try direct hook up to make sure it is the light and not the power source. Thanks for the input!
