👌M&R promises fitment of the light bars with the grille as pictured. If you have a different type of grille, please reach out with pictures for confirmation.

👍Our light kits are for off-road use only.

Choose your light bars colors:  

1) White LED -- Up to 15,000 lumens, bright and powerful. It will definitely provide you with enough light needed for all of your adventures. However, these are only for off-roading and can’t be used on the regular road. They will blind the in-coming traffic and also violates road safety.

2) Amber LED -- Up to 7,000 lumens, used in poor driving conditions such as dust, fog, snow and rain. It reflects through air particles much less than the white light. Therefore, making it ideal for poor driving conditions. For off road use only. 

3) dual function: main White LED light with Amber DRL backglow -- the white LED light is same as described above, but the amber DRL “daytime running lights” acts purely for aesthetics. Since it doesn’t give out much light, you can use this amber DRL feature on regular roads, it doesn't blind in-coming traffic.

WIRING

M&R Automotive doesn’t provide a wiring harness for this light bar kit. The light bar has 6ft of wire which is enough to reach AUX switches if your truck has them. Otherwise, you will need to purchase a generic wiring harness from Amazon/Ebay or create your own.

We now sell Wireless 8 Circuit Wiring Harness. This makes install much easier, no need to run any wires through the firewall, clean install.

Great light bars easy it install love the look and bright light my only complaint is your video says to reuse the factory screw for the bracket and that does not work by the time you put the bracket and the supplied washer the screw is too short had to run to hardware store for a longer screw I think for the price witch is good but along with the washer you should include 2 longer screw. I will say it is well built and great product thanks.

Thank you for the detailed feedback. I'll take a look at the design, add different length of bolts. Looks nice
