VisorLIGHT replacement bulb

Hi: I have a Donegan Optical VisorLIGHT which uses a LT-2204 Xenon bulb,same as this one:http://www.amazon.ca/Donegan-Optical-Company-Inc-Replacement/dp/B003K15I6C.I would like to replace it with something that produces more of a white light,as right now seems to be very yellow.Not sure if this bulb is made specifically for this visor or not,seems to be all plastic housing and it has the reflector built into the bulb.Hoping someone could recommend a LED bulb that would work. The original bulb runs off 2xAA batts,so not sure even if it’s a standard size bulb!?
Thanks,HB

EDIT-Seems I put this in the wrong section….should be in LED Light Bulbs section…Sorry!

After some thought,I don’t think a bare led bulb would do anything,maybe brighter,but probably way too floody,due to lack of a reflector which the stock bulb has. Maybe I can rig up a normal headlight somehow,giving me what I need. Thanks,HB
