Do you mean Fog Lights: Visit the auto department at your favorite Department store or one of the auto parts places (Pep Boys, Discount Auto) or J.C. Whitney
If you mean Daytime Running Lights.... (Which by the way I believe in) SEE-ME system is easy to install.. IF you can find it.. Alas, I've been unable to track it's maker the last few years. (I had one on my towed)
Home is where I park it!
