Review on SYLVANIA 1157 White Contains Bulbs by Chad Sornsin

Do not use these white SYLVANIA 1157 LED mini bulbs for boat trailer brake/turn signals. It does not illuminate the entire lamp body. It seems that only half of the lamp is lit. No light is emitted above this bulb. The light direction is oblique to the outlet. Boat trailer lights have the socket at an angle so that half of the lights shine towards the tires and the other half of the lights towards the engine have no light. general. In addition, the light does not come out from the bottom of the lamp, so the license plate of the trailer does not light up either. You really need an old style that shoots light in all directions for a boat trailer running/turn signal/brake light.
