Frequently Asked Questions
Q: Are these BMW F30 Reverse LED street legal?
A: Yes, these xenon white LED backup lights for the BMW F30 3 Series are perfectly street legal!

Q: What does LCI stand for?
A: LCI is short for life cycle impulse, a BMW term that applies to any vehicle and is another way of describing an automotive facelift. An automotive facelift means changes made to a car, truck, or bus's styling during its production run. This can include anything between interior design elements to mechanical changes. Using these LED side marker lamps retain the basic styling of your Mercedes while upgrading its functionality.

Q: How come the LED bulb flickers/strobes a couple times when I just start the engine?
A: This symptom is completely normal when installing any LED bulb for an European cars such as Audi, BMW, Mercedes-Benz, Porsche, Volkswagen, etc. This temporary flickering is caused by European cars' on board computer sending a routine check electrical impulse when first start the engine to all the bulbs and lamps to make sure they are not burnt out. Since LED bulbs are super sensitive to power, it will cause the LED bulb to respond and light up.

Q: I bought this BMW LED backup/brake light bulb for an upgrade. I took off my BMW's tail light housing but I'm not sure which one I need to replace. Which bulb do I remove?
A: First, make sure you removed the correct tail light housing (squared in yellow below), the one set above your bumper and NOT the casing on your BMW's trunk. The OEM bulb you will be replacing is the longer, tubular light bulb circled in red below and NOT the rounder, stockier light bulb next to it.

Q: Why am I still getting
error messages from my onboard computer?
A:
When first starting your engine, you will get what is called a “cold error message” which is a normal occurrence. Neither your LED bulbs nor vehicle have any issues.
The cold error message normally happens when you upgrade your stock bulbs to LED or even when using the stock bulbs in cold weather. When your LED diodes are not in use, your car will detect that they’re disconnected. Your stock bulbs experience the same event in cold weather, building up a strong resistance that virtually disconnects them from your car. In either case, your onboard computer will not detect your light bulbs and a bulb-out warning will show up.
When you first turn on your LED bulbs, you will find they will properly function and the error message will go away. Rest assured that there is no defect in your LED light bulbs or your vehicle.
