I'd certainly go halogen, if you have the alternator to handle it. I have a Compufire alternator, and my '97 came with these bullet halogen lights. I have some new ones to replace these though, same exact ones.
If you want to have something really awesome, try this. Regular running lights with H3 bulbs. Then put in a couple of these LED bulbs. Each is a small tower of 68 LEDs, which fits in a standard H3 lamp and the light that they throw out is absolutely unbelievable, with very little power draw. Here is the link for the bulbs:http://store.ijdmtoy.com/ProductDetails.asp?ProductCode=LED_FOG_H3_SKU_4F
