Relays, Fuses & Electrical Parts
Relays, fusible links, flasher units, key fob batteries and replacement fuses for Defender, Discovery, Range Rover Classic, Series III and selected later Land Rover models.
Start with the original part number and electrical function, then compare current rating, pin count or battery code where relevant. Relay and fusible-link fitment can split by vehicle, system and electrical specification, so use the product title and fitment notes together before ordering.

Find the right relay, fuse or electrical part
Relays and small electrical parts are normally matched by original part number and specification rather than appearance alone. Identify the component being replaced, then check its current rating, pin layout, colour coding or battery reference as appropriate.
| Job | Best place to start | Check before ordering |
|---|---|---|
| Replace a standard relay | Four-pin, five-pin and micro relays | Match the original part number, pin count, pin layout and current rating |
| Replace a high-current relay | Relays for glow plugs, ABS, air suspension and other higher-load circuits | Confirm the vehicle, electrical system and original relay reference |
| Repair an indicator or hazard-light fault | Vehicle-specific flasher relays | Check the original part number and vehicle fitment before ordering |
| Replace a fusible link | 30A, 40A, 60A and 100A fusible links | Match the original part number, current rating and colour |
| Replace a key fob battery | CR2025 and CR2032 button-cell batteries | Read the battery code printed on the old cell before ordering |
| Replace or restock vehicle fuses | Assorted automotive fuse sets | Match the fuse type and current rating specified for the circuit |
Check electrical part fitment before ordering
Relays with similar-looking cases are not automatically interchangeable. Use the original part number wherever possible and compare the electrical specification before fitting a replacement.
Original part number
Match the reference printed on the original relay, flasher unit or fusible link.
Match the reference printed on the original relay, flasher unit or fusible link.
Relay specification
Check the pin count, pin layout and current rating rather than relying on case size alone.

Fusible-link rating
Confirm both the current rating and colour against the original link.
Confirm both the current rating and colour against the original link.
Key fob battery code
CR2025 and CR2032 cells are different sizes and should be matched to the old battery.
