Its pretty hard to get adequate lighting out of a replacement LED bulb. Regular light housings are designed to reflect a halogen bulb, which throws out equal lighting in a 360 degree pattern. LED's are directional and throw light in a smaller and more focused beam.
For the best light output without wasting power, you want LED's in a specifically designed housing with appropriate optics. It is more money to buy, but the output is incredible.
My father-in-law has an Avenger with the standard halogen Bargman style lights. The "reflector" is more or less a flat piece of shiny metal heat shield. One light appears much brighter than the other. On my old RV, I replaced my Bargman light with a generic trailer LED stop/turn/tail from Harbor Freight tools. The lights are VERY bright and can be seen day or night. I'm one of those guys that drives with lights on all the time. When we camp in a group and caravan together, it is very easy for people to find me because my taillights are so bright.
