Review on 🚨 Xprite Red 4 LED 4 Watt Emergency Vehicle Waterproof Strobe Light Set - 2 Pack: Deck, Dash, Grille Surface Mount with Clear Lens - Police Light Head for Ultimate Warning by Daniel Evans

I've had these for about a month now. First of all, don't expect them to be as bright as the LEDs in ambulances. Remember that you pay $9 each, one of the ambulances will easily set you back $200 each. That's not to say they don't work well, they work well for what I use them for, the 4th flashing brake light. Be sure to seal them. I installed them without applying silicone around the socket where the wire comes out and where the clear plastic meets the base. Now they have moisture in them, but they still work. The warranty is unclear so I'll either open them up, dry and seal them or just wait for them to get past me and buy another pair because of course they're so cheap this time. If you plan on buying them, cover any spots you think water might get in with silicone, which you can buy at your local hardware store.
