mercedes-benz 123 series Bulbs

At GSF Car Parts we have a huge choice of the most common bulbs to suit lots of different makes and models. Here you'll discover bulbs for a range of applications on your vehicle. 

We’ve got high-quality headlight bulbs, which will provide excellent illumination when out on the road at night, and a range of extra-bright fog light bulbs for driving in poor conditions. We also stock replacement brake light bulbs, indicator bulbs, tail/stop lights, spotlight bulbs, number plate light bulbs, daytime running bulbs, and ballast switches.

We source premium bulbs from leading automotive manufacturers, such as Ring, Osram, and Neolux, so you can be assured that any replacement bulb you buy will be durable and reliable. You can quickly search for the correct bulbs for your car by filtering your reg number or by selecting your make and model. 

If you can’t find the car bulb you need here, it might be in our all bulbs section where we have a larger range of common and uncommon bulbs for your vehicle.

What kind of bulbs are used in cars?

Our range is extensive, so whatever type of car bulb you’re looking for, you'll find it with us. If you’re looking for something energy efficient, then be sure to go for one of our LED car bulbs. These offer an exceptionally bright white light and will drain less energy from your car battery, too.

There are three main types of bulbs used in vehicles. These are:

Halogen Bulbs

Halogen bulbs are the most common bulbs you'll find in a vehicle today. Halogen bulbs are fitted to most cars because they're more cost-effective to manufacture offering a cheaper replacement than other bulb types.

They're more affordable than Xenon or LED bulbs and at GSF Car Parts we stock a huge range of halogen bulbs for every make and model.

LED Bulbs

LED bulbs are an extremely bright and long-lasting option for your car. They are highly energy-efficient using less power from your vehicle's battery. 

They tend to outlast halogen bulbs and are around 150-300% brighter. They last up to 10 years but tend to be more expensive than halogen bulbs.

Unfortunately, although it is legal to have LED bulbs internally in your car, there is no legislation to approve the use of replacement LED lights externally. And since 2021, MOT testing centres will now fail LED upgrade bulbs unless they were fitted by the manufacturer.

Xenon Bulbs

Xenon HID bulbs have a xenon gas which is 300-450% brighter than standard halogen bulbs and they can come in different colours. They should be replaced around every 3 years and in pairs. 

Like LED bulbs there is currently no legislation for Xenon bulbs to use legally as replacement bulbs in your car. Unless fitted originally by the manufacturer.
