Additional considerations when replacing E90 3 Series reverse bulbs

Conventional Bulb vs. LED Bulb

Newer cars have adopted LED technology for most of the lights, not only for the cabin but also for exterior lights. Not that long ago, conventional, incandescent bulbs were the standard not just for tail lights and interior lights but also for headlights.

The BMW E90 is one of those cars equipped with conventional bulbs from the factory. LED light upgrades are available for tail light bulbs and indoor and courtesy door lights.

Incandescent bulb vs LED bulb

LED bulbs are generally much brighter, and more durable, with a longer life expectancy than conventional incandescent bulbs. The price difference is almost marginal, so people are turning to LED instead of incandescent bulbs.

Would LED Replacement Bulbs Bring Any Error Codes?

For all replacement bulbs above, you will not have any error codes in your car’s system since all of those bulbs are equipped with CAN-BUS chips specially designed to prevent any errors.

Replacing the original or OEM-style reverse light bulbs with LEDs is known to result in error codes when using old LEDs that are not designed for modern vehicles with bulb monitoring like the E90. However, that happens with no-name brands and products with no integrated chip or resistor.
