How to choose car and motorbike accessories without costly mistakes: a practical guide to lighting, navigation and maintenance

Choosing a new accessory for your car, motorbike, scooter or moped often seems straightforward. Yet many disappointing purchases are caused by three recurring pitfalls: the product does not fit the vehicle, a marketing claim says little about real-world performance, or an important component is missing. This applies to LED car bulbs, motorcycle covers, phone holders and even cordless tyre inflators.

When comparing car and motorbike accessories, it is therefore wise to start by considering compatibility, technical specifications and usage conditions. The following checks will help you make a more informed purchase.

Three common pitfalls when buying car accessories

1. The fitting or vehicle compatibility is not checked

An H7 bulb will not automatically fit every headlamp. The same applies to H8, H9 and H11 LED bulbs. Always check the fitting, the bulb position and the vehicle’s requirements. On some European models, including certain Volkswagen, Mercedes-Benz and BMW models, a CANbus decoder may be needed to reduce error messages or flickering.

With BMW LED headlamps, you should also check the model range, production period, connector and mounting points. A product described simply as “for BMW” is not automatically suitable for every BMW.

2. A high number is mistaken for better performance

Claims such as “500% brighter”, “100,000 lumens” or an exceptionally long lifespan are product claims. According to the brand Roadsun’s own research, the H7 bulb in question is said to be up to 500% brighter than a standard halogen bulb. This is not a universal guarantee for every car or lighting unit. Light output also depends on the reflector, alignment, lens and condition of the headlamp.

When choosing LED car bulbs, therefore, do not look at lumens alone. Also consider colour temperature, beam pattern, cooling and correct alignment. After installation, the headlamp may need to be realigned to prevent dazzling oncoming drivers.

3. Waterproof, sturdy or cordless does not mean limitless protection

A waterproof motorcycle cover can help shield your bike from rain, but it must be the right size and securely fastened. An oversized cover can flap in the wind, while an undersized one may leave parts of the motorcycle exposed. A suction-cup phone holder will not perform equally well on every surface either.

With cordless accessories, also check the power supply. A cordless CarPlay screen for a motorcycle works differently from a phone holder with wireless charging. “Cordless” usually means that the phone connects without a data cable; the screen or holder may still need a power supply.

Important parameters for car and motorbike accessories

Fitting, connection and installation

Before placing your order, make a note of:

  • the vehicle’s make, model and specification;
  • the correct bulb fitting, such as H7 or H8/H9/H11;
  • the space available behind the bulb;
  • the connector, power supply voltage and any CANbus requirements;
  • the mounting method and viewing angle for a screen or phone holder.

A bulb with plug-and-play installation can be convenient, but still check whether the LED chips need to be positioned horizontally and whether there is enough room for a fan.

Materials and protection

With a motorcycle cover, dimensions, seams, fastening straps and material construction matter more than the word waterproof alone. According to the product description, the Oxerbog cover uses aluminium foil needle-punched felt with a water-repellent coating, double-stitched seams and wind buckles. Always allow a motorcycle to cool down before putting the cover on; hot exhaust components can damage the material.

For a tyre inflator, maximum pressure, airflow, battery capacity and units of measurement are all relevant. According to the product specifications, the AstroAI L7S has a maximum pressure of 150 PSI, an airflow rate of 17 litres per minute and a 4,000 mAh battery. The manufacturer states that the model is not intended for off-road vehicles, motorhomes, lorries or trailers. Always check your tyre pressure against the vehicle manufacturer’s recommendations.

Safety and regulations

Jack stands are not an accessory that should be assessed on specifications alone. Check the load capacity, minimum and maximum height, vehicle category and stated standard. The TCE jack stands are offered with EN 1494 certification and an adjustment range of 388 to 580 mm. Always use two suitable stands on a level surface, and never rely solely on a trolley jack when working underneath a vehicle.

With lighting, the beam pattern must remain correct. Also check whether installation and use are permitted on public roads. A product description alone does not replace checking the applicable Dutch vehicle and traffic regulations.

Useful additions for everyday use

A magnetic car phone holder is practical for navigation, but check whether your phone or case requires a magnetic ring. The Oxerbog magnetic holder is foldable, adjustable through 360 degrees and designed for smooth surfaces. A vacuum or adhesive base will only hold securely when the dashboard is clean, grease-free and suitable for installation.

For tyre maintenance, a cordless tyre inflator such as the AstroAI L7S is useful to keep in the boot or on your motorcycle. Set the desired pressure, check the correct unit and let the inflator switch off automatically when that function is available. Larger vehicles may require a more powerful electric air compressor.

If protection is your main priority, you can choose between a motorcycle cover measuring 220 x 95 x 110 cm or 245 x 105 x 125 cm. Measure the motorcycle with its mirrors and accessories before ordering. A waterproof motorcycle cover is not a substitute for a dry, well-ventilated storage space; allow a wet cover to dry completely before storing it.

Frequently asked questions about car and motorbike accessories

Which LED car bulb do I need?

That depends on your vehicle’s fitting and lighting function. Check the instruction manual or the existing bulb. H7 is not interchangeable with H8, H9 or H11. Also check the available space, CANbus requirements and whether the bulb is legally suitable for use.

How long does an LED bulb or cordless tyre inflator last?

Lifespan varies depending on the product and usage conditions. Brands may state an estimated lifespan; according to information from Bullvision and Roadsun, some LED bulbs are rated for up to 50,000 hours. This is not a guarantee for every real-world situation. With a tyre inflator, charging cycles, temperature and frequency of use affect battery life.

Can I use a motorcycle cover outdoors all year round?

You can if the size, fastening and ventilation are suitable. Secure the elastic straps and wind buckles, avoid contact with a hot exhaust and allow the cover to dry before folding it away. Regularly check the seams, buckles and key openings for signs of wear.
