Tons brighter. Wish I could use better bulbs or hid.
I put Philips XtremePower 9006 lows and OSRAM Night Breaker 9005 highs in my stock headlight assemblies. Those, with a 12 ga 4HI wiring harness, and polished lenses made a huge difference. Both are Euro market bulbs, can be a bit hard to find, but Amazon often has them in stock.
