Higher the Kelvin rating the whiter and brighter the light!
Careful! The base is the same as an 1157, however the 1157 is a dual filament lamp. Look inside the socket single pin is an 1141, dual pin is a 1076


Kelvin temp relates to the COLOR of the light spectrum NOT how bright it is. 2700 or so is in the yellow spectrum, 5K or so more like daylight and more white, then as you go up more towards blue end of the spectrum.

Brightness is measured in LUMENS. It's easy to have a 2700K bulb appear and be much brighter than a 5000K bulb.

For the first few years or RVing, I replaced tungsten bulbs with LED. When I wanted even more and better lighting, I found it was cheaper, easier and overall better to replace fixtures. I have replaced single bulb fixtures with dually switched lights.

good summary but I will "quibble" with the statement "the higher the color temperature the WHITER the light will be". as you go up from 2700 K or so color does appear whiter but as it continues up it goes from "white" to bluish, not whiter and as you get to around 7000K light definitely is IMHO not white but bluish.

Thank you everyone who responded, I had no idea all the different information there is about LED lighting.
