These are top quality Halogen bulbs. Rediculously bright, double a standard bulb! We use these in our own scooters and every rebuild we do. These also fit Vespas that take the BA20D 'Bosch' type bulb fitting.
Please note: You need a glass or polycarbonate lens to use these bulbs, or they will melt or discolour it!
DO NOT TOUCH THE GLASS ON THE BULB, USE THE SHROUD PROVIDED. THE NATURAL OIL ON YOUR FINGERS WILL BLOW THE BULB!!!
