Relay for sure. I upped the wattage of my bar from 300W to 420W by extending it, so that is going to be between 15-20 amps depending upon system voltage. Given that, I'll use a 30A relay, which is a standard cube relay, but make sure the coil side is 24V. Relays for rear defrost grids and...

Thanks. That is a good idea. I'll consider it before I reassemble it.

Eastbound and down...

One of the light modules. They are chained together to feed power through, in addition to a leap-frog of power wires so lessen the load on each solder bridge. It was configured this way initially, so I simply continued it.

*This spot reserved for something cool in the future.*

Thanks bud. Sorry for the hang up. We'll get through this, and then everybody will be able to do it also. Full width LED light bars front and rear for $200! When I had it on, it was like having the sun screwed onto to your truck. Pics coming as soon as we have it working correctly. It's...

I'm ok with the wiring right now. I want to get the lamp modules working correctly and then conduct a measurement, and size accordingly. Each LED is 3W, and there are 140 of them. Just FYI. Stay tuned, thanks.

Thanks for the input Tim, we'll see. It is way louder than it is supposed to be and the LED's flicker also when on 24V. On 12V, the light is silent and non-flickering if I use one ground wire, but not another which I added, but at 12V it is sucking about 40A like it should be so I can't run it...

Well, a short term set back. The light bar is together (sans lens) and works, but makes a loud buzzing/hissing sound when supplied with 24V. On 12V, there is no noise. The bar is supposed to be able to handle 12-30V range. It seems as if one of the voltage regulators on one of the light...

Just received tracking info that the custom size polycarbonate lens is due to arrive March 23rd.

Here is the 70" LED light bar assembled with all reflectors, just waiting for the lens to arrive. Also included a shot of the difference of flood vs spot reflectors. Flood reflectors are on each end, with spot reflectors in the middle.

I have the light modules in and soldered up. I upgraded the power wires going to the unit to 12ga, but I may have to upgrade them further yet. The light bar is now 420W, so at 24V that is nearly 20 amps. When I power the light bar up, it works and is crazy bright, but it is flashing slightly...

Just ordered the custom cut polycarbonate sheet for the lens. Nice user-friendly website, and the new 70" long piece was $10 cut to size. Oversize shipping charge from UPS ($17), so $27 total. http://www.tapplastics.com They had them in color tints, reflective mirror finishes, smoked...

LED light modules added, not wired together yet. Bar is now 70" long, and 420 watts of LED flood and spot lamp power, 24V. Next up is to wire the modules together, test it, and then screw in the reflectors. Then, wait for the 70" x 2-3/8" x 1/8" polycarbonate lens to arrive and install it...

I could not find one this shape, plus I would need the light modules to extend it, the lens fastening bars, the reflectors, etc... It only made sense to buy two and jam them together. It is going well though, exactly as I thought. The welding was low cost and should hold just fine. These are...

You can have this one for $900 and a case of Corona's. :hammer:

Just eBay search 52" or 54" LED light bar. That's it, they are all the same on there, and all coming from the same place, so grab one that ships from within the US and has free shipping. Price is down to about $115 or so each. And they are 24V ready. So for $230, I now have one front and...

Sorry, late for an update. Our local TIG welder is supposed to be one of the top in his trade (Chris Razor, Hi-Tech Welding in Plymouth, MI, featured on Miller's web site), so he was booked 3 weeks out. Finally got the light bar back, TIG welded together as a single unit now, 70" long. He V...

Took the 50" and 20" extruded light bar housings into the TIG welder today to be combined. He quoted a week, just FYI. Gives me time to start considering mounting options using the windshield frame vs cab roof sides. Can't wait to get it back, assemble, and mount it. Looks easy to do a flip...

Made the housing cut to combine today. So when disassembled, each LED light module is exactly 10" long, and contains 20 lights (10 in each 2 row). Each reflector is 2"x2" (4 reflectors per cube), so there are 5 reflectors on each light module. The reflectors are available as spot or flood...
