Because tail light # STL42RB has more than one function it has more than one amperage draw rating. Brake lights and turn signals draw more power so that will be the higher draw at 0.413 amps. Running lights use less power and would be the 0.26 amps.

If you have the running lights on and then step on the brake, the brake light overrides the tail light. If you have the brakes on (with or without the running lights on) the turn signal will override the brake light on that side. So the most the light could draw at one time would be 0.413 amps.

For this light you will also need wiring pigtail # A45PB. I have included a video review of this light for you.

Voltage can also vary on the vehicle. A higher or lower voltage output will also vary the amperage draw.
