Not as bright as big name brands... and far less expensive. Durability vs weather not an issue for me, as mine are mounted inside existing OEM corner light housings. Bright enough for my purposes (security). Low power draw is a big plus, as I routinely leave engine off with lights running for extended periods. All wiring, power source, and control box were pre-wired, so install was simple. Soldered a cigarette plug onto the power leads and just plugged it in.
