didn't know where else to ask this

Don't know where to go for this info, so came here:

Can I direct substitute a 1156R LED with a filament type 1156 bulb? Some
sources speak to a resistor between the bulb socket and the LED. But, I'm
wondering if the resistor is built into the 1156R LED, since it obviously
plugs into the same socket the 1156 filament type bulb does.

Where's a good place to find an inexpensive socket for the 1156 bulbs?

LEDS need a resistor. It is illegal to manufacturer your own LED light bulb for cars exterior lights unless it is DOT approved.

Ok, I misread the post.

The resistor should be on the bulb itself. You should be able to just put in a filament type bulb. All autoparts stores have them.

What I'm trying to find out is if I can simply plug an LED bulb into a socket in place of a 1156 bulb.

if it is designed to do so, then yes.

What I believe you have is an bulb using LEDs made to directly replace a standard incandescent bulb.


If it already has the base from an 1156 bulb, then I would think that is exactly what you have.

sockets: should be available at any local auto parts stores

Remember:

LED lights are illegal unless the light itself is DOT approved.

The "R" stands for red. These bulbs have built in resistors and are a direct plug in to a standard 1156 socket. They are fairly expensive and I didn't see anything about meeting DOT standards in the ads I checked.

Thanks goldstar. That's the info I was looking for.

It's for a homebuilt trailer sidelight for putting light on the ground around the sides so I can check the loads at night.
