I was under the impression that they have to be DOT approved. I was going to use the OEM tail lights on that 40 bumper, but I liked the idea of LED's as many of you guys have here.
I don't know how the DOT department creates approval on all these safety components, as my seatbelts are probably not. Most likelly, they all come from China.
I also was contemplating on putting these on the bumper, as they are slick in my opinion, but way too pricey!

Generally, anything that's DOT approved will say so on the lens, if not on the packaging.
Technically, anything that doesn't meet the DOT's requirements cannot be sold unless labeled for offroad, or industrial use only.
If you buy from a retailer that supplies for road use, they will generally have a warning label, or the salesman will be required to mention if they are non-compliant.
This is because, if you unwittingly buy non-DOT lights, and I hit you; for example, your insurance company could either stick you with the responsibility, or if the insurance company learned a retailer sold you an illegal light wihthout your knowing, you can sue them. It's all liability.
Also, you will be sold stories by sleezy retailers that something might be "as good as DOT approved" or "would be DOT approved, but the manufacturer hasn't had time (or some such lame excuse)" this is a steaming pile of first-rate bull crap used for an underhanded sale.
There is no "almost DOT" certification. the part either passes or fails, and usually part that fail do so because they use cheap components.
I played with some non-DOT LED lamps recently, and they had poor-quality resistors in them that burned up with regular use within two months. Those kind of failures are hard to cover up, and many cops will see dimmed lights, fogged lenses, or burned-out sections of LEDS, and give you a warning (if they're friendly) or a fix-it ticket.
Been there, done that, done with getting sold down the river by untrustworthy sources.
That said, I trust Truck-Lite products, exclusively, because they will disclose that information on either the item, the package, or the MSDS.
