Multi Use Blackout Caps - Pack of 100
Available for Purchase(Donner says "YAHoooOOOooo!")
The most unique and versatile black out cap available, these black out caps can be use on a variety of different types of lights including LED M5, M6 and 5mm as well as incandescent mini lights. They are pliable enough and intended to stretch over the base of the bulb creating a seal that will block 100% of the light from coming through. Sold in packs approximately 100 caps - packaged by weight.
If you are having problems with these caps slipping off the bulb, then you are not sliding the cap all the way over the base of the bulb as they were designed. Or you are using them on non standard or T-lock incandescent mini light strings which will usually not fit. Please review this article for more information:
