If you install bulbs with the same Wattage as the stock ones you wont have to worry about melting any wires… since current draw will be the same. PIAA makes a quality aftermarket bulb. I have used several types with good results and reliability.

You can also use high wattage bulbs if you install a relay in the harness.  
Personally I would get aftermarket projector housings and put a HID kit in them. More work but a great result.

What is the brightest halogen bulb?  
For the 55W marked segment, sorted in order of brightness:  
+50%: Philips Vision Plus (achieves its extra performance by increased luminance, not lumens. See this article: [http://www.eur.lighting.philips.com/press/automotive/resultsVision.shtml](http://www.eur.lighting.philips.com/press/automotive/resultsVision.shtml))  
+30%: Philips Premium, Osram Silverstar (European marked only - see note below)  
+20%: Osram/Sylvania Xtra Vision, Osram/Sylvania Silverstar (North american marked only - see note below)  
+0%: Philips Bluevison, Osram/Sylvania Cool Blue, Osram/Sylvania Halogen Plus, and OEM bulbs like GE.  
-10%: PIAA Superwite
