Thanks for the reply! I did it and it works great. For those of you who are curious how to do this on a 98 Accord, I'll explain what I did. Check your manual for how to change the side marker or parking light bulbs. For me this involved popping out a rivet that holds the plastic shield in the wheel well. Then, I reached inside and pulled out the light bulb. It has three wires. I peeled back the plastic on the red one and spliced in the red wire that runs from the back of the switch. After that, I put it back together and was good to go. This way it only works when the parking light or headlights are on. And, I can have it on with just the parking lights, which is especially important since my normal lights blind me in heavy snowfall.
