Those are some nice looking lights. I haven't seen one of those old strobe light bars like you have in a quite a while. Our sheriff's office used to use that style. My PD has gone to the Liberty LED series from Whelen and I think that is what the county guys are using now. My ambulance service has a wierd mix now. Still have lots of strobes but they are the large box mounted ones. They still have one with an old JetSonic. I think that bar draws more power than some alternators will put out.
I was looking at the LED off road lights, just not sure what I want or how I want to do it yet. I had a really nice set of IPF lights that worked really well. I had them first on my white 99 Dually and transferred to behind the grill on the green outdoorsman, between them getting older and not wanting to go through pulling them, I just left them on the green one when I traded it.
For now I have several sets of the old rubber housed tractor lights sitting around and I am going to put them on for auxilliary backup lights. I figure that takes care of me for the moment and then if I decide to upgrade I will already be wired up and just need to make the swap.
What brand are yours? Seems like name wise I am finding the Cree and Ridgid alot and then quite a few that look like knockoffs. I will have to do more research before I decide what to go with.
