My cforce 550 EPS EFi has Bulb type HB3 or 9005 :-) on both low-beam and high-beam :-) I recently purchased and replaced the stock 60w halogen low-beam bulb by LED 90W, 9200 lumen and 6000 kelvin. For the High-beams I chose 100W 6000 kelvin xenon kit. LED in low-beam is definitely recommended by me coz of the difference from that of the stock halogen bulbs. No doubt about that! The xenon on the other hand is a very good upgrade from the stock halogen bulb but I found out that it has a considerably long delay when turning the light ON. The igniting process of the bulb takes about 15 to 25 seconds and it is at full brightness and color after about a minute from the time one switched ON. Så am thinking of changing it by LED real soon. :-)
