Do a complete retrofit. I've installed SC430 projectors in my truck and I can tell no aftermarket kit can hold a candle to it. If you can't find any SC projectors, any S2000 witha little modifications will look goodAside from replacing the high beam lamp Im done with Lexus lights. Like I said above my next step will add on lighting for both low and high. If I could just match the lighting output of my 80 series I would be a happy driver.
