Hi. I'm just after the Measurement between the mounting Bracket holes when the brackets are turned outwards. Thank you
wondering how wide the mounting holes are apart when using the side brackets on the 41.5 inch st3k
Do these ligHts come with a channel in the top of the fitting to mount or is it only the side brackets to mount With?

These light bars are the real deal
Review by chad
I purchased a 41’ single row bar a year ago and am still surprised on how well it works, so well that when driving on outback roads if i need to dip my lights its such a contrast its like my 17 ranger xlt parkers are only on... it takes a bit for my Eyes to adjust from having so much light down to just low beams.
I was planning on a set of spotties but havent needed them as yet as this bar lights far enough.
I have just ordered a set of stedi low beams for the ranger to help.

Very happy.

Ohh and another great feature is StedI lights are a good color not a silly 6500k blueish light, the 5700k is much easier on the eyes and personally i think i can see much more than if it was the 6500k. (Posted on 5/09/2018)

ST3K 41.5 INCH 40 LED SLIM LED LIGHT BAR and Wildtrak roof Brackets
Review by Brock
Let me start by saying that i have had alot of lights, from chinese junk to top brand usa gear. Stedi takes the cake, not just for the lights but for the entire package from quality to light output to mounting hardware to wiring. i have this light with the wildtrak roof rail mounting kit, ive had other roof kits and lights that mount above the windscreen on the pillars and they are no good for your daily driver, the wind noise and the resonation from the cooling fins makes them UNBEARABLE. this setdi setup eliminates both of those problems in a neat, tidy, quality solution, the light output is amazing , its exactly what i wanted it to be, i COULDN'T be happier. Thank you stedi. (Posted on 23/08/2018)

Easy setup
Review by Fridgy
The light bar does everything i need it to so very happy. Best thing was the supplied harness. Aside from some wires being a tad shorter than i needed the harness itself made setup so much easier than any other lights i have done in the past. Great product. (Posted on 12/04/2018)
