Difference in Amperage Draw Between 1157 Incandescent and LED Bulb

Published 01/15/2019

Question:

what is the power draw for an incandescent bulb vs LED bulb in this trailer? I saw the post for a 921 bulb, and the bulbs in my trailer are standard old style stoplight bulbs with the switched leg going to a little button on the bottom and the common being the metal on the side of the bulb. I believe the bulb is a 1157 bulb

It depends on a few things as it's not a standard difference but typically an incandescent 1157 will pull around 2 amps whereas an LED like the part # CM93236 pulls around 0.2 amp.
