I have removed the switch and bezzel portion of the light assembly by cutting the plastic at the light lens with a utlity knife. I mount and wire the remaining components in existing incandescent fixtures. I have experienced huge reductions in battery charging cycles for interior lighting. I have utilized both the red and white light fixtures. These lights pay for themselves immediately. I have also utilized them in my RV in the same manner.
