A little mount I designed for a 10mm OD halo I had laying around made for the Axial SCX24 Gladiator (May also fit JLU, I am not sure if the grille is exactly the same). You will need to drill or ream out the lexan headlight hole in the body. I reamed to about 8mm, just enough to show most of the halo and hide the heat shrink around the halo. Attach the halo mount to the body with shoe goo, just be careful to not get shoe goo on the headlight lenses or outside of the body. If you run my inner fenders you will need to trim those as shown in the picture. The inner fender files and the halo headlights are NOT included in this purchase. You can find the Halo headlights here: https://www.ebay.com/itm/391329375821
They are also available in different colors on eBay, Amazon, Ali Express, etc. As long as they have an OUTSIDE diameter of 10mm (5mm center LED) they should work.
