ENERGY STORAGE Road lights are available in both battery and capacitor models, with the capacitors being much longer lived, around 3-5 years for batteries, 10-15 for capacitors. They are housed in aluminum and/or polycarbonate casings and can withstand the pressure of trucks driving over them. APPLICATION Use adhesive (or in some cases screws) to secure them to a surface. Some models have a post to prevent slippage.
