The Osram silverstar H4's are more than enough for main bulbs, with no worries of melting wiring. Look at Osram all-season H3's for a yellow/gold bulb. The Sylvanias with the same name are not exactly the same bulb, only buy the Osrams if you can. I recently paid $57 for a pair of H4's and a pair of H3's. Great bulbs and not expensive.
