The best H7 LED headlight bulbs for your track car

While not street legal, a H7 LED bulb is a bright upgrade off the road

A car's LED headlights turned on

Headlight technology has come a long way in the last few years. From the halogen bulbs of old, there are now LEDs, HIDs and even lasers being used on posh Audis. All of these lights are more powerful than conventional headlights and use less power to run and look cooler. In short, they sound like a no-brainer upgrade for almost any car.

Problem is, cars that were not fitted with such headlights from the factory are not legally allowed to be retrofitted with LED bulbs. For more information on why we’ve got an article on general headlights for your car here.

And as cars that come with LED lights as standard will require a dealer to replace the bulbs, it means these bulbs can only be used in special circumstances.

LED headlight bulbs therefore can only be used on racetracks and off-road. So, if you own a track car you won’t be using on the road or a mud-plugging 4x4 and are wanting to upgrade your bulbs, we have the perfect options for you.

The reason you can’t retrofit LED headlights to a car is that there is no legislation to regulate or test these bulbs. Current legislation tests the filament that an LED light lacks meaning it isn’t covered. And as all bulbs require a British Standard mark to be legal, they are illegal to fit into your car. And because they're brighter, it's easier for them to dazzle other drivers if they aren't adjusted correctly.

What does H7 mean?

Headlight bulbs come in different styles depending on what they do. H7 simply means these bulbs are single filament units with two prongs on the back.

How do I fit a H7 bulb to my car?

Obviously, every car is different and there will be some variation in how to add the lightbulb but here is a general guide to how to replace your bulbs. Always check your car’s handbook first, however.

One: Make sure your car is turned off before you lift the bonnet.

Two: Locate where the headlights are (it should be fairly obvious) and find where the bulbs are.

Three: Disconnect the three wires in the back of the bulb. These may be held on with clips, screw caps or a small catch. It is then a case of undoing the locking mechanism to retrieve the old bulb.

Four: Insert the new bulb and reattach the wires. Halfords recommend wearing gloves to avoid the oil on your skin from damaging the bulb. Make sure the bulb is properly aligned and you should be good to go.

Five: Some cars are more complex than others to work on (accessing the headlights on the second-generation Renault Megane required you to remove the entire front bumper for example).
