LED, HID & Replacement Light Bulbs

Choosing replacement bulbs

Read more: choosing LED, HID and replacement bulbs

Start with the lighting system already installed. For a serviceable headlight or fog-light housing, identify its bulb code and application before comparing LED headlight bulbs. Check the product’s listed base compatibility, cooling clearance and any adapter requirements.

For an existing xenon system, browse HID replacement bulbs using the exact bulb designation. A halogen bulb, an LED replacement and an HID bulb are different product types; the same general lighting purpose does not make them interchangeable.

Choose the function before the colour or style. The signal, brake and interior bulb collection includes multiple bases and colours. Confirm the socket, contacts, single- or dual-function requirements and the exact listing’s application notes.

For turn signals, review any hyperflash or vehicle-electronics requirements. For interior and reverse-light applications, check the physical space and required bulb type. Compare package quantities when replacing more than one lamp.

Have your vehicle’s make, model and year, the current bulb marking, and a photo of the socket ready. Verify the housing has not been changed, then compare the bulb base, electrical specification, connector, available clearance and intended lighting position.

Read the selected product’s installation instructions and intended-use information. If you are comparing Diode Dynamics LED options, see our SL2 vs SL2 Pro guide for model-specific cooling and application checks. If you need a complete lamp, start with the headlight size collections.

Light bulb FAQs

How do I find the correct replacement bulb size?

Check the marking on the installed bulb and the vehicle or lamp manufacturer’s documentation. Confirm the lighting position: low beam, high beam, fog, turn signal, brake, reverse or interior. If the housing has been changed, identify the bulb required by that housing rather than relying only on a model-year lookup.

Can I replace a halogen bulb with an LED bulb?

Start with the exact LED product’s application information. A matching base alone does not confirm housing compatibility, beam performance or permitted use. Check space for the bulb’s cooling components, the dust cover, retaining adapter and connector before choosing a replacement.

Are HID bulb types interchangeable?

Choose the exact designation required by your installed HID system. The collection includes several D-series and H-series options; do not select one simply because it looks similar. Confirm the bulb, connector and ballast requirements against the product and system documentation.

Will LED signal bulbs need resistors or other adapters?

Requirements vary by bulb and vehicle. Some LED turn-signal replacements can cause rapid flashing, often called hyperflash, and may need a compatible resistor or flasher solution. Other products have their own compatibility features. Follow the exact product’s installation instructions rather than adding parts automatically.

How should I choose the colour of a signal or brake bulb?

Match the required lighting function and the product’s guidance for your lens and application. The collection includes amber, red, white and decorative options; not every colour is intended for every exterior lighting position. Check the stated intended use before ordering.

Does a higher colour-temperature number mean a brighter bulb?

Colour temperature, stated in kelvin, describes the appearance of the light rather than its brightness. Compare the exact product’s output information, beam application and installation requirements separately from its colour-temperature rating.

Are bulbs sold individually or as a pair?

Package quantity varies. Check the selected product and variation for the number of bulbs supplied and whether adapters, drivers or ballasts are included. A collection photo does not establish what comes in every package.

Do I need a replacement bulb or a complete headlight?

Check whether your existing lamp has a serviceable bulb. If you need a complete lamp rather than a bulb, browse universal headlights or truck-specific headlights, then confirm the exact fitment.
