To help protect your lightbulbs when used in exterior installations where the bulbs are exposed to precipitation, we recommend installing them pointed downward (best), or outward (2nd best).

If bulbs must be oriented in an upright position, where the bulbs are most vulnerable to moisture penetration at their seams, we highly recommend using inexpensive socket gaskets.

Available for both E12 and E17 standard Christmas light sockets. 

*Not compatible with Tru-Tone Deluxe light strings or other non-standard style sockets.
