Frequently asked questions about the Car lamps category
What are car lamps and what are they used for?
Car lamps are vehicle lighting components that provide road illumination, signalling and cabin lighting; the category includes halogen (H4, H7, H1, H11), LED and speciality bulbs. They differ by base type (H4, H7, BA15S, BAY15D, T10), power and application: low beam, high beam, fog, indicators and interior lights.
What is the difference between H7 and H4 lamps and which is right for low beam?
H7 is a single-filament bulb commonly used for either low or high beam; H4 is a dual-filament (12V 60/55W) bulb combining low and high beam in one P43t base. Choose H4 only if your headlight has a P43t socket for combined function; choose H7 when your vehicle has a dedicated H7 fitting.
What LED car lamps are available and what are they used for?
LEDs include T10 and 30mm interior bulbs, BA15S/BAY15D signal types and performance HYPER LED 10W and 3W bulbs. They are ideal for daytime running lights, position lights and cabin lighting, offering low power draw and long life; when replacing halogen headlamps verify reflector compatibility and vehicle electrical support.
Which bulb bases (H1, H4, H7, H11, BA15S, BAY15D, T10) are in this category?
The range includes H1, H4 (P43T), H7, H11 headlamp bases and BA15S, BAY15D and T10 for indicators, position and interior lamps. Always check your vehicle manual or the existing bulb marking to confirm the correct base before purchase.
How to choose between halogen and LED for position lights or interior bulbs?
Choose LED (T10, 30mm, BA15S LED) for lower power draw and longer life; choose halogen for a traditional warm colour and plug-and-play compatibility. Check physical dimensions (e.g. 30mm for some T10s) and socket type before fitting.
Are HYPER LED 10W bulbs suitable to replace halogen headlamps?
HYPER LED 10W are performance replacements in some applications, but check compatibility with your headlamp optics and vehicle electronics first; they can alter beam pattern so ensure they meet your vehicle's lighting requirements.
What does the marking 12V 60/55W on an H4 P43T bulb mean?
12V 60/55W indicates a 12-volt operating voltage with two power ratings: 60W for high beam and 55W for low beam; P43T denotes the bulb base type. It means the H4 bulb provides combined high/low beam functions from one socket.
How to identify the correct bulb type from the old bulb or catalogue?
Check the marking on the existing bulb (e.g. H7, H4, BA15S, T10) or consult your vehicle handbook; the category lists bases such as P43T for H4 and dimensions for T10/30mm types to ensure correct fitment.
Are 21W BA15S bulbs suitable for indicators and how to choose the colour?
21W BA15S bulbs fit indicator and rear lamp sockets when the base matches; choose orange (ORANŽ) for indicators and red for rear stop lights, ensuring the colour matches the vehicle's original lighting specifications.
Can I use H1 12V 55W bulbs in my car headlamp?
Yes, provided your headlamp has an H1 fitting and the electrical system supports 12V 55W. Always confirm the fitting type and power requirements in your vehicle handbook before installation.
How durable are LED bulbs compared to halogen ones in this range?
LED bulbs in the range are generally far more durable than halogens, using less energy and lasting longer under normal use. Exact service life depends on the model (e.g. HYPER LED, T10 LED), operating conditions and vehicle electrical system.
