I'm looking at getting either a 40in or a 50in led bar and I was wondering if I will need to get a 2nd battery. I currently have three 7in halogens hooked up and I want to make sure adding the bar wouldn't be too much of a drain.

Also does anyone know of a good way to mount the 40in to the stock roof rack.

Thanks

Doubtful. The led's are great because they use very little power to operate vs halogens. Are you still going to run the halogens with the light bar?

The halogens are on my bumper and I plan on keeping them until I upgrade to LEDs for that too.

You're fine running that on a single battery.

Dual battery setups start being useful when you're running something like an ARB fridge for long periods when the alternator isn't supplying power.

The alternator output is the real question. If you exceed the alternator capacity then no battery amount will save you. Dual batteries are great for insuring that battery draw down doesn't get you to where you need a jump start. If you do a LOT of winching or run electrical while the engine is off then a dual battery is the right move.

What he said. You should upgrade the alternator first if you need more power. A second battery is only good if you plan to run things for a long time with the engine off.

In your case you should be fine. Just keep an eye on the voltage meter.

Thanks for the help. Has anyone mounted a 40in bar to the roof rack?

How's the wind noise? That's the way I'm looking to mount it but a little lower on the rack

The faster you go the more noise and vibration, but you get use to it. I've had it up to 80 with the light bar and it's noisy, but no other problems so far after a year and a half. Lower would likely be better, but the mounts weren't wide enough to mount it too much lower. I'm planning to put a windvisor on the rack, and then attach the light bar to the windvisor as low as I can (Just need to find the time to put it on).

If I were to do it again, I'd probably do a 50" curved and get mounting brackets that integrate with the roof rack mounts:

reszfab.com/product/fj...ets-holes/

Or you could try something like this instead:

I've been looking at this 40in mount from reszfab

reszfab.com/product/fj...light-bar/

I emailed them to get pictures of it mounted because I don't want it to look funny sticking out that far. I've been considering the 50in curved too but I like the look of the 40in

I got my 40" from Desert Rat. It's very bright and has held up well so far. It was about $250 if I remember correctly.

40" curved bar off ebay

They dont draw very much amperage, mine is rated at 40amps or there-abouts.



used these tusk roll bar mounts, had to grind the mounts a little where the light mates to them to get the angles adjusted for an even mating surface. like 10$ a piece on ebay. Use some star washers and luck washers to keep things from moving around.
