LB, PIAA regular wattage Xenon( 60/55 ) bulbs do put out more light than the stockers. Used one on my 98 SRX ( single bulb light )and it made quite a difference. They are more money but I think they're worth it. The RX-1 has two bulbs and works very well in stock form. I wouldn't risk using higher wattage bulbs in it as they're really not necessary. I think you will be very happy if you just put in a couple of PIAA 60/55 bulbs. Even with the stock RX-1 lights some of my buddies complain about the shadow it causes in front of them when you come up close behind them. I'd hate to hear them bitch if I had a couple of 100 watt bulbs in it. Stick with the 60/55 in a quality brand light and you will be happy. Too many cheap China imports out there. I've even heard of bootleg PIAA's, so make sure to buy them from a reputable dealer.
