D4S HID xenon bulbs · 2-pack

Detail

Product details

Refresh your existing D4S HID headlights with this pair of new 35W xenon replacement bulbs. A 6000K cool-white appearance, aluminium alloy construction and a one-year warranty make this a practical replacement for a matching HID system.

Product details

For matching D4S HID xenon systems only. A vehicle model may have different headlamp options, so confirm the existing bulb code rather than relying on make and model alone. If you are unsure, send us your vehicle details and a photo of the original bulb marking. HID systems use high voltage; fitting by a qualified technician is recommended.

Features

Features

• D4S replacement fitting for vehicles already equipped with a matching HID xenon headlamp system.
• 35W rated power per bulb and a 6000K cool-white colour temperature.
• Two new bulbs supplied: replace as a pair to help keep the colour appearance consistent across both headlights.
• Aluminium alloy construction with a supplier-stated IP67 protection rating.
• One-year product warranty.
• Uses a compatible HID ballast; this is a replacement bulb, not a halogen-to-xenon conversion kit.
• Match the exact marking on your original bulb. D-series fittings are not interchangeable.

Returns

If you’re not happy with your item or you’ve changed your mind.

We want you to be happy with your purchase. If you need to return something, contact orders@ttrpracing.com with your order number and the item details, and we’ll help you through the process.

Under 14 days

• Tell us you wish to cancel within 14 days, starting the day after you receive your goods. You then have a further 14 days to send them back. You can request an exchange, subject to availability.
• You pay the direct return costs for a change-of-mind return. We recommend a tracked service and appropriate insurance. Keep proof of posting.
• You may open the packaging and inspect an item as you would in a shop. We may deduct for loss in value caused by handling beyond what is necessary to check its nature, characteristics and functioning. Opening the packaging alone does not remove your cancellation rights.
• Return all supplied parts and packaging where possible. Pack the item securely in an outer box; avoid attaching courier labels or tape directly to the product packaging.
• Include your name, order number and contact details so we can identify your return. A returns form or a reason for cancelling is not required to exercise your statutory cancellation rights.
• We do not charge a restocking fee. For a statutory cancellation, we refund within 14 days of receiving the goods or evidence you sent them back, whichever is earlier. We refund the item price and standard outbound delivery paid; any extra paid for optional premium delivery is excluded. Refunds use your original payment method.

After 14 days

We do not offer change-of-mind returns where you first notify us after the 14-day cancellation period. Your rights for faulty, incorrect or misdescribed goods are separate and continue to apply.

Exclusions from change-of-mind returns

The cancellation right does not normally apply to goods made to your specifications or clearly personalised, including genuinely bespoke cut-to-length items. Any applicable exclusion will be identified before ordering. A standard product being ordered from a supplier or described as a “special order” does not, by itself, remove your cancellation rights. These exclusions do not affect rights for faulty or misdescribed goods.

If your product becomes faulty.

Contact our customer service team with your order number and a description of the fault. We may suggest basic troubleshooting or manufacturer support where helpful, but this does not replace your rights against us as the seller.

Under 30 days

• If goods are faulty, not as described or unfit for their agreed purpose, consumers normally have a 30-day short-term right to reject them for a refund. You can ask about an exchange instead.
• Contact us for return arrangements. Include a description of the problem and your order reference. We will inspect the item and cover reasonable return carriage for a valid faulty-item claim.
• If we cannot reproduce a reported fault, we will discuss the findings and next steps with you. We will explain and agree any proposed charge before incurring it; your statutory rights remain unaffected.

After 30 days

You may still be entitled to a repair or replacement and, where the legal conditions are met, a price reduction or refund. We will carry out a statutory repair or replacement within a reasonable time, without significant inconvenience and at no cost to you, including necessary postage. Your rights are not limited to the manufacturer’s warranty. We can also help with a separate manufacturer warranty where supplied.

Damage, installation and wear

Damage caused by misuse, incorrect installation or normal wear is not a manufacturing defect. An exclusion applies only where it caused the problem being claimed for. We recommend professional installation where appropriate; this does not remove your statutory rights.

How to contact us or cancel

Email a clear cancellation statement to orders@ttrpracing.com, including your name, address, order details and delivery date. You can also write to Trading Parts UK Ltd, 19 Heathfield Rise, Rishworth, Sowerby Bridge, HX6 4RS. Contact us to confirm return instructions; our approval is not required for a statutory cancellation.

This consumer policy applies to new direct website orders from 27 October 2026. Any longer returns period promised when you placed an earlier order remains available. Marketplace purchases follow the marketplace support process; business orders follow the terms agreed in their quote. Your statutory consumer rights are unaffected.
