LED Number Plate Bulbs Buying Guide

Festoon bulbs or DE3175 are the bulbs used to lighten up your number plate during the night. The majority of vehicles will have a cheaper halogen bulb in order to brighten up the number plate.

Upgrading to a xenon white LED license plate bulb will modernize the rear of your plate and is a direct replacement. Like with any modification, there are a few factors you should consider before purchasing.

Canbus Error Free

An error message appearing after fitting a new light bulb to your car can be very irritating. You have the choice to use the new LED bulb with the error message or have the hassle of taking the bulb back out and returning the bulb, which is fairly time consuming.

The Canbus error allows components to communicate through a single or dual networked data bus. Due to LED bulbs using very little power, some car computers may detect that the bulb is broken and will then show a warning light.

A Canbus error free bulb have built-in load resistors that prevent any error codes or warning lights appearing. All of the recommended led festoon bulbs above have canbus error free functionality. If you are driving a classic car, the need for this functionality is not essential but the majority of people will prefer the classic halogen style if you are a true classic car enthusiasts.

Bulb Installation

Installation can be achieved within minutes depending upon your car. The hardest part of the installation is removing or getting to the bulbs via the license plate holders. The majority of the cars uses a simple screwdriver to pull the lenses over the bulbs.

Once you have got to the bulb, its a direct swap unless you have bought the wrong size festoon bulb. Usually it will require a bit of a push to get the bulb in. If it is not working, try switching the sides over (flipping horizontally). Another common mistake are many people will point the 180 degree of light the wrong way (facing upwards and not downwards at the license plate).

LED v Halogen Bulbs

The benefits of LED lights has been widely spoken about with performance, reliability, instant light and many other benefits. Upgrading to the best LED headlights you can get your hands on is the most common beginner modifications. However, installing xenon white license plate bulbs are even easier and provide an excellent white light at the rear of your vehicle..

Switching the bulbs will provide a modern/stylish look, more light at the rear of the car and other benefits. The main reason for the upgrade is usually for the added styling that can make such a difference on certain makes and models.


Spending that little bit more on canbus error license plate bulbs that produce solid xenon white light is worthwhile. Cheaply made festoon bulbs can begin to flicker after a few hundred miles of use as well as giving off a poor quality white light. Many claim to be canbus error free but you can use a professional diagnostic tool to try to remove the light bulb error with no luck.

We strongly recommend choosing a high quality LED license plate bulb such as the Philips Vision white festoon bulb that provides a 12 year guarantee and has the backing of the Philips brand reputation.
