Do LED reverse lights need resistors?

You need to fit load resistors on each indicator light and possibly stop, tail and reversing lights as well. These load resistors need special mounting to ensure the component does not overheat and cause potential fire hazards.

Do LED bulbs work with reverse polarity?

If LEDs are reverse-connected to a sufficiently low voltage supply it is possible that they will simply conduct no current, emit no light and suffer no damage. In such cases correcting the polarity will result in correct LED operation with no adverse effects.

Which is brighter 912 or 921 bulb?

The 912 and 921 bulbs are interchangeable as they have the same T-5 wedge base. The 921 has a wattage of 16.8 and draws 1.4 amps. The 912 is 12 watts and draws 1 amp. So the 921 should burn brighter than a standard 912 bulb.

Can reverse lights be LED?

Besides the safety benefits, LED reverse lights simply look great. This is especially so if LED tail lamps are already installed — the brightness of both lights will give your vehicle a uniform look.

Do I need a load equalizer for LED backup lights?

Expert Reply: When changing from incandescent or halogen type bulbs to LEDs, load resistors are required.

What will happen if an LED is connected in the wrong direction?

LEDs, being diodes, will only allow current to flow in one direction. And when there’s no current-flow, there’s no light. Luckily, this also means that you can’t break an LED by plugging it in backwards. Rather, it just won’t work.

Will 194 bulbs fit 921?

Re: Using a 921 bulb in place of a 194 for license marker? It would definitely melt the lens and can cause damage to the socket as well.

What is the wattage of a 921 bulb?

18 Watts and 12.8 volts.

Are reverse light bulbs universal?

Reverse lights on a vehicle must be white in color, and these come standard on all vehicles.
