A week or two ago I posted photos of some interesting modular LEDs I saw at SEMA:
They have a hexagonal shape and can be stacked/assembled into many different combinations, including a horizontal light bar or a 7-led hex cluster as shown above. They're very small, about 2" diameter. They're similar to KCHilites "flex" LEDs - the flex lights are square and these are hexagonal, but otherwise they're similar.
The manufacturer says each light puts out 1000 lumens, so just one of these isn't far from a stock JK low beam headlight which is about 1100 lumens.
I've been thinking about different ways those LEDs could be stacked and used on a Jeep, here are a few. Obviously you wouldn't have all of them on a Jeep like the illustrations below, but rather than posting a dozen different concept drawings with one light set each I've put lots of them on each Jeep for the purpose of illustration...
The company that manufactures these modular lights doesn't make mounts for any of the ideas above except the longer horizontal light bars (10", 20", 50") and the 7-led cluster, but mounts could easily be designed for any of the above. I've come up with a way they can be arbitrarily linked together into any combination - straight line, angles, triangles, etc. so any of the configurations above would be easy to bolt together.
As far as I can tell these hex LEDs aren't generally available in the Jeep market in the US yet but the manufacturer is looking for US distribution.
