These bulbs are designed for higher voltage lights, including those that operate on NiMH batteries. The bulbs have a standard BM base style for use in 5100 Wheat Style Headlamps. The BM12 (12V30) will perform great in a 17 or 21 volt light, with very little problem of bulb failure, while the 12V32 is ideal for added brightness in 21 volt NiMH lights. The 24V98 is best rated for use in 28+ volt NiMH battery systems. All of these bulbs are high quality two filament bulbs that feature a high and low beam.
