The Invincibell X Lightbox is a unique visual deterrent that will slide into the cover and will illuminate the front of the Invincibell X at night to maximize its security impact. In addition to the low light illumination the Invincibell X with light box will strobe from the base and the lightbox when the alarm is activated, giving a visual indication to those around, should the alarm activate.

With sealed electronics and enhanced 3 way tamper protection you can be confident that the Invincibell X with Lightbox will be there if you need it.
