Replacement 1157 LED Bulbs for a Travel Trailer

Question:

I recently purchased SMD 18 LED replacement bulbs from another supplier for my travel trailer. I was very disappointed with their lack of brightness especially in turn signal mode. How can I be sure that these will perform any better? Are these DOT approved?

First, what a lot of people do not know about LED lights is that if you are using them behind a red lens then the LED bulb needs to be red as well. Otherwise you will end up with a dim pink light when using white LEDs.

LED bulb # P231157R360 is a pair of red LEDs so they would work well behind a red lens. When used as stop, tail, turn bulbs behind a red lens they are DOT compliant.
