Frequently asked

How do I know a part will fit my car?

Enter your registration above and we cross-check against the TecDoc catalogue to narrow the list to car electrics and car lighting listed against your vehicle. Specifications can still vary between trim levels and engine variants, so we recommend confirming the part dimensions against your existing component before fitting.

What brands do you stock?

We stock established manufacturer brands sourced through trade channels. The brand row at the bottom of this page shows which manufacturers we carry for car electrics and car lighting. We don't sell unbranded parts.

How quickly will my order arrive?

Most orders dispatch from our Northampton warehouse within 1–2 working days. Free standard delivery on orders over £40 to most UK mainland locations.

What if the part doesn't fit?

Please check our returns policy for the current terms. If you're unsure about fitment for your specific vehicle variant, please contact our team before ordering using the details at the bottom of the site.

Can I check fitment before ordering?

Yes — every product page shows whether the part is listed against your selected vehicle. Where multiple sizes exist for the same vehicle, the dimensions are shown so you can compare against your existing part. If you're unsure, contact our team for help confirming the right option.

Bulbs, batteries and electrical parts

Electrical and lighting parts are some of the most frequently replaced wear items — headlight bulbs typically last 1-3 years depending on type, batteries 3-5 years in normal use, and other parts like alternators, starters and sensors are catch-it-early items.

Common signs to replace

  • Dimming headlights or a yellower beam — bulb output is dropping; replace in pairs (UK MOT requires matching).
  • Slow cranking on cold mornings — battery or alternator.
  • A dashboard warning light that wasn't there yesterday — pull the OBD code before guessing at the cause; many parts can throw the same warning.

Bulbs must match by pair

UK law requires both headlight bulbs to match in colour and output. Replace as a pair even if only one is failing — the second will follow soon and a mismatched pair can fail an MOT.
