Yes, and it says this in the description:
-"This LED is designed to withstand a wide operating voltage range for RV Camper Trailer Motorhome 5th Wheel and Marine Boat."
Something is wrong in the description in the Amazon link above if you read the actual description text.
"1156 / 1141 Base LED Replacement Bulb 300 LUMEN 10-24v Natural White - Beam pattern: 120 degree. -Description- -Bright 300 Lumens, 1156/1141 wedge base 120 degree angle bulb -Built with the finest LED lighting technology and materials. -Wide Voltage Range: 10-18 Volt DC"First is states 10-24V and then it states 10-18V.
Which voltage range is it?
Granted 18V will be "compatible" with RV charging systems that have possibility as much as 15V, it doesn't leave much room either..
That is a narrow voltage range and indicates that it is a cheaper LED that uses a current limiting resistor or nor current limiting at all.
Generally you should be on the lookout for the ones that state 10V-30V as those are using a switching power supply setup in current limiting mode.
Ones using current limiting resistor or no current limiting will vary in brightness with variations of the voltage and tend to run rather hot when run at upper limit voltages..
All one can do is buy a small qty and try it.. If it doesn't work, try a different one. I quit recommending specific brands as they come and go like the wind..
