Choosing car accessories: practical upgrades without the wrong purchase

Car accessories can make your vehicle more comfortable, smarter or more practical. Think car interior accessories for added comfort, car electronics for everyday convenience and car safety accessories for unexpected situations. However, not every product is suitable for every car. A universal connection, a high lumen rating or a promising battery life doesn’t always tell you enough.

These are some common pitfalls:

  • Compatibility is presented too broadly. An accessory may be described as universal, but still not fit your dashboard, air vent, seat type or vehicle system.
  • Specifications are quoted without context. For example, a higher resolution on a car dash cam doesn’t automatically mean number plates will be clearly visible in all lighting conditions.
  • Installation requirements are listed at the bottom of the product page. A 24-hour parking mode for a dash cam may require a separate hardwire kit. And a 12V accessory isn’t necessarily suitable for a 24V commercial vehicle.

Check these specifications before buying

1. Power connection and vehicle compatibility

First, check the supply voltage. Many car accessories run on 12V, while some vans and lorries use a 24V system. According to the product description, the Dreamcolor interior lighting is designed for 12V cars, SUVs, vans and pick-ups. A suitable voltage converter is needed for 24V vehicles.

When choosing car electronics, you should also check phone and vehicle integration. A wireless CarPlay adapter will usually only work if your car already supports wired CarPlay or Android Auto. A standalone Android Auto screen can be a practical solution for an older vehicle, but it often needs a clear space on the dashboard and a 12V to 24V power connection.

2. Dimensions, mounting and range

Measure before you order. This applies to car cup holders, seat covers and screens, as well as LED strips. For an air vent mount, check the shape and sturdiness of the slats. For a centre console cup holder, the diameter and depth of the existing recess are important.

For car interior accessories, check:

  • the space available around airbags and controls;
  • the length of cables and any extension leads;
  • how the accessory is fitted: with a clamp, adhesive, suction cup or by placing it in an existing recess;
  • the temperature range if the product will be left in a hot car.

An adhesive strip can be handy, but it may not stick as well to a dusty or greasy surface. Clean the surface and allow an adhesive-mounted product to set fully before driving.

3. Use, maintenance and regulations

Don’t look only at the purchase price. A car battery charger may be suitable for AGM, GEL, EFB and wet lead-acid batteries, but you still need to check the battery capacity. According to the product information, the EAFC charger is designed for batteries from 4 to 100 Ah and must be used indoors, protected from rain.

For car LED lighting, the fitting is only one thing to consider. Also check the light colour, beam pattern, CANbus system error messages and regulations for lighting on public roads. According to the product description, Bullvision bulbs aren’t recommended for certain vehicles without an additional CANbus decoder, including some models from Volkswagen, Mercedes-Benz and BMW. So check your vehicle documentation and local approval requirements before replacing bulbs.

A dash cam or mirror accessory mustn’t unnecessarily obstruct your view. Position equipment so the driver has a clear view, and only adjust settings when the car is stationary.

More comfort and ambience inside your car

For a subtle upgrade, car interior accessories such as a car air freshener, seat covers or ambient lighting are easy to combine. According to the product description, the Dreamcolor LED strip works with an app, Bluetooth control and multiple RGB modes. The kit is designed for 12V and can be fitted along dashboard seams, doors and footwells.

When installing, make sure cables are kept clear of the pedals, steering system and airbags. With a car air freshener, fragrance strength is a matter of personal preference; also check that liquid can’t leak onto plastic or upholstery. A seat cover must be suitable for the type of head restraint and mustn’t interfere with side airbags.

Frequently asked questions about car accessories

Which car accessories are useful for everyday driving?

A car cup holder, a phone or CarPlay solution, a dash cam and a suitable battery charger are all practical choices. Start with the problem you want to solve, then check for extra features such as lighting, app control or multiple charging ports.

Will a wireless CarPlay adapter work in every car?

No. Your car will usually need to support wired CarPlay or Android Auto already. Also check your phone’s compatibility, the USB connection and the manufacturer’s vehicle list. An Android Auto screen with its own display can be an alternative for cars without a built-in system.

How long does a car accessory last?

It depends on the materials, use, heat, moisture and maintenance. Recharge a jump starter regularly, protect electronics from prolonged heat, and check mounts, cables and battery contacts periodically. This helps reduce the chance of an accessory being unavailable when you need it.
