LED light bar BEHIND the windshield?

Thinking about what it would take to mount an led bar behind the windshield INSIDE the cab at the very top of my windshield. I know some cop cars have the strobes inside the cab. Anyone know what the enclosures look like? sheet metal with foam seals?

I know it'd be easier to mount on the ouside and wouldn't look bad but I'd like to continue the sleeper status on my build. Here's what it'd be going in.

You should mount it facing rearward so you can burn your eyeballs out and then walk into on comming traffic.


Wow people are really that stupid?

It seems like a good idea, one less thing to be broken off or stolen.

You are correct, a sheet metal housing with foam or rubber seals. I will try to get a picture for you.

A few pictures of how they look installed on a pickup. You could build a similar housing or shroud to fit most any commercially available Led light bar. This one doesn't have a seal around the windshield area, but you get the general idea of how it works and fits .

Awesome! Thanks for the pictures! Im wondering how much deflection the windshield causes when trying to focus and aim. Im gonna have to borrow a small bar and play around a bit.

What's so retarded about it? Other than the possible glare (which could probably be solved with some type of foam surround) I think its a glorious idea.

With led's you would not have to worry about heat and in a fullsize rig there is plenty of room if you keep it tucked high to the roofline.

Build it up sir. I want to see what it shows.

Even without a foam surround and the blue/reds strobing away at night, glare is minimal. The only issue I see would be beam pattern cutoff along the lower edge due to the long bottom shroud. Probably best to stick with a spot lens, or angle it down slightly. The range will be reduced slightly, but that should be ok for most vehicles.

Another vote for build it.

Cutting off the beam on the bottom sounds like a benefit with that white hood.



Maybe 2 separate bars would be better, one on either side of the rear view mirror? Similar to:

I don't think you are going to get projected distance behind the glass.

I dont like splashback from roof lights hitting the hood. I've had a bit of seat time in a truck with two 40"s on the roof. The long shroud on the bottom woul be benifitial like some of you mentioned. The two 10"s in the grill ar spots so the large bar or 2 or 3 small bars I think id fit with combos. Tracing the pattern for the shroud is gonna be a son of a bitch. ...

It won't be too difficult. Build a mockup out of poster board. Use a transfer scribe (google it, easy to make) to trace the contour of your windshield.

X2, trace from the outside of the glass. Just hold up to the glass and have marks, and how far the glass is away from that mark at a 90 degree angle.

Then just measure, mark, connect the dots and cut. You'll have a mirror image of the glass.



Interested to see how this works out. My truck is a DD and stays outside all the time and theft is the number one reason I haven't gone to LED's. I also like the sleeper look

I would not do this. A: LEDS make a ton of heat and B: You will loose light output going through another layer of glass. Over 10%

Led bars need a good amount of airflow to stay cool. If they get too hot they will start cutting current(light output) to stay cool. They can reach temps upwards of 165F. I sure would not want that in my cab.

This is probably the answer you don't want to hear. High output lighting gets hot, regardless of the source. And a big badass lightbar is going to be no exception. It might not be so bad if you've always got the defrost A/C going, or windows down or something...

but, heat....you will notice it.

Inset them in your roof line with appropriate shield to prevent glare on the hood? Just work.

I have a buddy who works with rigid. Once my bank account recovers from the giant wave of bills that hit me this last month I'll start bugging him about heat output. Theres no sense in me bugging a whole bunch of people if I can't pull the trigger on buying from them.

The heat out put on rigids is nothing compared to a holigin light. I have @ 50 inch 20 inch and a bunch of dullys scattered accross my vehicals. I can hold my hand on the lights while they are on.

Btw this sounds like somthing im going to try !! Good idea

I install these on police and Marshalls for a living and they work perfectly. You just need to buy quality. LEDs do not get hot. You will be mounting off your visors. They perform very well. You just have to mount it close enough to the glass that you don't get light reflecting back but not so close that it rattles. Go with code 3 or federal signal. They both make very good solutions. I have seen them light up a city block. I will put it this way. If it didn't work, the Marshalls wouldn't spend 10s of thousands on us to install them.

Here is a new Police vehicle interior lightbar, that has both a warning and takedown (flood) mode. This has the shrouding like the other interior lights, but they use the shroud as a heat sink as well. If you look at the second photo you can see that the board is sitting on the bottom of the shroud, and it uses a reflector to project the light. This uses six 3 watt LEDs per module, and works very effectively as a flood light.


Here is a Video showing this as well.

We use those style led strobes on customer vehicles all the time. I, and I think the OP, are more interested in using this as a constant "ON" driving lamp.

More interested in seeing, rather than being seen.
