Buy cars & bikes South Africa: electronics and accessories that actually fit your vehicle
If you searched for buy-cars-bikes-south-africa expecting parts and accessories, Communica can help with the electronics, sensors, wiring and tools that make vehicles safer, smarter and easier to maintain. We do not sell whole vehicles, but we stock hard-to-find components - dashcams, tyre-pressure sensors, CAN-bus adapters, 12V power modules, lithium battery management parts and wiring looms - with local availability and same-region pickup options to keep projects moving.
Why choose local stock for vehicle electronics
Buying locally matters for vehicle projects: lead times under a week for many lines, VAT invoices for fleet procurement or student projects, and branch collection in Samrand, Pretoria CBD or Cape Town to avoid failed delivery and customs delays. For branch locations and hours, see our branches page here.
Typical products and who they help
- Aftermarket dashcams and mounting kits for commuters and ride-share drivers
- 12V power supplies, DC-DC converters and fuses for custom audio and lighting installs
- CAN-bus and OBD-II adapters for telemetry and fleet diagnostics
- Sensors (accelerometers, hall-effect, GPS modules) for DIY trackers and e-bikes
- Connectors, heat-shrink and wiring looms for clean, serviceable installs

Compatibility and specification callouts
Vehicle electronics demand correct voltages, fuse ratings and mechanical fit. When selecting parts, confirm these core specs:
- Operating voltage: 12V nominal vs 24V systems - use DC-DC converters where required
- Continuous and peak current ratings - match wiring gauge to expected load
- Connector type and pinout - note many OEM systems use manufacturer-specific housings
Quick reference table for wiring and fuse sizing:
| Load (W) | Current (A) = W / 12V | Recommended fuse (A) | Wire gauge (AWG) |
|---|---|---|---|
| 12W | 1.0A | 2A | 20-22 AWG |
| 60W | 5.0A | 7.5A | 16-18 AWG |
| 240W | 20.0A | 25A | 10-12 AWG |
Use Ohm's law to verify inline resistor choices or sensor pull-ups: I = V / R. For example, a 5V sensor with a 10k pull-up draws I = 5 / 10000 = 0.5 mA - negligible for typical vehicle telemetry circuits.
