[QUOTE="Ruger, post: 1509380, member: 1594"] Two things: You are very likely to use your fog lights most when on the road and they therefore should be DOT compliant. You don't want to spend a bunch of money on your new fog lights only to incur the ire of your local constabulary and then spend more money on a citation, on replacement DOT compliant lights, or both. Read product description/box. (Note: There is no such thing as DOT [U]approved[/U] lighting. The US Department of Transportation does not test and approve automotive lighting. They issue specs, and manufacturers may or may not follow those specs. If they do, they will tell you that their lights comply with DOT guidelines. If they tell you that their lights are DOT [U]approved[/U], they are lying.) You will want to choose whether to go with LEDs or halogens depending upon where you live. Halogen lights produce enough heat so that accumulating frozen road gunk melts and slides off the lenses. They are, in effect, self-defrosting. LED fog lights, being more efficient, do not produce enough heat to do that. So if you live where snow and ice come with winter driving you would be well advised to choose halogen fog lights. As fog lights are mounted low on the vehicle they sure do tend to pick up more freezing spray from other vehicles on the road, so this is more of a concern for fog lights than for driving lights. One other thing: the Society of Automotive Engineers (SAE) and the US Department of Transportation are not the same folks and do not necessarily communicate nor agree. Also understand that your state is empowered to enact legislation more stringent than the DOT's guidelines. For example, in Nevada it is illegal to have more than 4 white light emitters pointing forward on your vehicle, and that includes the factory headlights. Do your homework. [/QUOTE]
