Choosing car accessories: practical tips for dash cams, lighting and roadside breakdowns

Car accessories can make your daily drive more comfortable or come in handy if you break down. But there’s a huge choice, and many products look similar. A high lumen rating, a large screen or a powerful jump starter doesn’t automatically mean an accessory is right for your vehicle.

This buying guide explains what to look for before you buy car accessories. We cover everything from a car dash cam and wireless CarPlay displays to LED car bulbs, a tyre inflator and a car emergency kit.

Common pitfalls when buying car accessories

1. Marketing claims without checking your vehicle

Words such as “universal”, “300% brighter” or “suitable for all cars” don’t always tell you enough. For lighting, first check the bulb fitting type, such as H4 or H7. For a display, check the power connection, audio options and smartphone compatibility.

For example, according to its product description, ENdureLite claims its H4 bulb is highly compatible. This is a claim made by the brand. Check the fitting, available space and any error messages yourself, using your vehicle or bulb handbook.

2. A missing component you only notice after buying

A dash cam without a microSD card may not be ready to use straight away. Some models need a separate hardwire kit to use parking mode. A CarPlay display may support a reversing camera without including one as standard.

Always check:

  • Whether a microSD card is included.
  • Whether a power cable, mounting bracket and audio connection are included.
  • Whether a hardwire kit is needed for dash cam parking mode.
  • Whether a jump starter needs to be fully charged before first use.
  • Whether an LED bulb needs a CANbus decoder.

3. Looking only at peak specifications

A jump starter with a high peak current isn’t automatically suitable for every engine size. Check the stated petrol and diesel engine capacities, battery voltage and charge level too. For a portable compressor, a digital pressure display, hose length and power source are just as important as the maximum pressure.

Resolution is only one factor when choosing a dash cam. Dash cam night vision, field of view, storage, G-sensor and Wi-Fi transfer also affect how practical it is to use.

Key specifications to compare

Dash cam: footage, storage and parking mode

A car dash cam with one camera records the road ahead. A dual-channel model also records traffic behind the car. According to its product description, the 70mai Dash Cam A200-1 uses two 1080P cameras, has a 130° field of view and a 2-inch IPS screen. The microSD card isn’t included.

When choosing a dash cam, consider:

  • Resolution and frame rate: higher values can capture smoother footage with more detail, but they also use more storage.
  • G-sensor: can mark footage if there’s a jolt or collision.
  • Night recording: terms such as Night Owl Vision or HDR refer to features in the product description; actual results also depend on the windscreen, lighting and installation.
  • Parking mode: check whether a hardwire kit is required and how the car battery is protected.
  • Privacy: check local rules on recording in public places, and don’t keep footage for longer than necessary.

LED car bulbs: fitting, beam pattern and regulations

H4 LED bulbs are generally used for both main beam and dipped beam. H7 LED bulbs are often used for dipped beam, main beam or fog lights, depending on the vehicle. Always check the original fitting and the space available behind the headlight.

Key things to check:

  • Does the bulb physically fit the fitting?
  • Is there enough room for a fan or heat sink?
  • Is a CANbus adapter needed to prevent error messages?
  • Does the headlight need to be realigned?
  • Is this combination approved for road use in your vehicle?

According to its product description, Roadsun claims its H7 bulb has a 6500K colour temperature, IP68 protection and a built-in fan. These are the supplier’s product specifications, not a guarantee that every car will produce the same beam pattern. Have the beam pattern checked after installation, and make sure you don’t dazzle oncoming drivers.

CarPlay, Android Auto and motorbike navigation

A wireless CarPlay display or Android Auto screen can be useful if your car doesn’t have these features as standard. Check which iOS or Android versions are supported, how sound is played through the car speakers and how the display fits on your dashboard.

For motorcyclists, water resistance, controls and readability matter more than a wide range of entertainment features. According to its product description, the ESSGOO 5-inch motorcycle unit supports wireless CarPlay and Android Auto, has IP67 water protection, Bluetooth 5.3 and a TPMS setting. Use navigation and voice controls in a way that keeps your attention on the road.

Roadside assistance: jump starter and compressor

A car jump starter can help get a flat 12V battery going, but it won’t diagnose a faulty battery or charging system. Check the maximum engine size it supports and charge the booster according to the instructions.

A car tyre inflator or portable compressor is especially useful for adjusting tyre pressure. Use the recommended pressure shown on the car’s door pillar or in its handbook, rather than relying only on the maximum PSI shown on the pump.

Frequently asked questions about car accessories

Which car accessories are useful for long journeys?

A car emergency kit could include a jump starter, tyre inflator, jump leads, hi-vis vest, torch and basic tools. Choose products that suit your vehicle, and check the charge level of an electronic booster regularly.

Is a dash cam with parking mode always ready to use straight away?

No. Many models need a separate hardwire kit. Also check whether the camera supports a suitable microSD card and how files are locked. A camera with a G-sensor can mark footage of incidents, but check the settings after installation.

How long do LED car bulbs or a portable compressor last?

Lifespan depends on use, heat dissipation, moisture and installation. Manufacturers may claim a long operating life, for example, but that’s the brand’s estimate rather than a guarantee for every vehicle. Keep the compressor dry, charge its battery regularly and replace LED bulbs if the beam pattern or performance changes.
