❓ Frequently Asked Questions (FAQ)

Q: What does “T10 / 501 / W5W” mean for bulb type?
A: These designations refer to standard wedge‑base automotive bulbs. “T10” indicates the bulb’s shape and base size, “501” and “W5W” refer to the original 5‑watt wattage rating and wedge‑type design — common for side markers, licence‑plate lights, parking lights, or small interior lights.

Q: Where can I use these bulbs?
A: T10 / 501 / W5W bulbs are commonly used for parking lights, side‑marker lights, number‑plate lights, interior courtesy lights, glove‑box lights, boot lights and other small signal or utility lights on most cars.

Q: Are these bulbs standard for a wide range of vehicles?
A: Yes. Because the T10/W5W wedge base is very common across many makes and models, these bulbs are compatible with most cars that specify W5W / T10-type bulbs — but always check your vehicle’s manual or existing bulb to confirm.

Q: What are the benefits of buying a 100‑pack rather than single bulbs?
A: A bulk pack reduces per‑unit cost, ensures you have spare bulbs on hand for multiple vehicles or frequent maintenance, and is convenient for workshops, garages, or fleet owners. You won’t need to reorder frequently and can replace bulbs immediately as needed.

Q: Is installing these bulbs easy — can I do it myself?
A: Yes — replacing T10/W5W bulbs is generally a simple DIY task: remove the light lens or bulb holder, pull out the old bulb, and slot in the new wedge‑base bulb. No special tools required in most cases.

Q: Are these bulbs suitable for both interior and exterior use?
A: Yes — these bulbs are designed for low‑power lighting applications typical in both interior (courtesy, boot, glove‑box) and exterior (side markers, plate lights, parking lights). Just ensure the light housing is rated for halogen bulbs and sealed if used outdoors.

Q: Will these bulbs meet legal or safety requirements for number‑plate / side‑marker illumination?
A: In many regions, as long as the bulb matches the required specifications for your vehicle’s lighting system (correct wattage, fitment, colour temperature), T10/W5W halogen bulbs are acceptable. Always check local regulations and ensure lenses and housings are intact.
