Colour Temperature

Colour temperature is measured in Kelvin (K) – the lower the number, the warmer the white light appears, while a higher Kelvin will appear cooler. Colour temperature generally ranges from 2700-3300K (warm) to 3300-5300 (cool) – and 6500K is daylight.

Equivalent Wattages Between Different Light Bulbs

As long as the technology developed, a LED light bulb can only use 8 watt power but light up similar brightness when a incandescent light bulb uses 60 watt power. There is equivalent wattage between different light bulbs. To stop making confuse, you need to know what wattage equivalent to each other. See the table attached as below.

⚠️ Important: These are 12V automotive bulbs for a compatible 12V vehicle electrical system. Do not connect them directly to 240V mains or a 24V vehicle circuit. The compatible vehicle circuit supplies 12V; a separate household transformer is not normally part of installation.

Frequently Asked Questions

Are these 21W wedge bulbs dimmable or compatible with electronic vehicle controls?

Dimmability and compatibility with PWM, bulb-failure monitoring or aftermarket controls are not confirmed. Use only the vehicle manufacturer's approved lamp and control arrangement. Each bulb is listed as a single-filament 21W lamp, not a dual-intensity 21/5W stop/tail bulb. The dimming field remains blank.

Will these wedge bulbs fit my vehicle's stop lights?

Match the exact vehicle and lamp assembly's specified 12V supply, 21W load, single-filament design, wedge-base dimensions, contact arrangement and physical clearance. The photo confirms a glass wedge base but does not establish a standardized cap code or dimensions. Wedge appearance alone does not establish compatibility. Do not use directly on 240V mains or a 24V vehicle circuit; a compatible vehicle circuit supplies 12V without a separate household transformer in normal installation.

How many bulbs are included, and how do they differ from 21/5W bulbs?

The existing listing specifies two 21W single-filament bulbs per retail pack, for a combined rated 42W when both operate. Unlike a twin-filament 21/5W bulb, each has one listed 21W filament rather than separate stop and tail filaments. The supplied image shows one bulb only and does not independently confirm pack quantity or full electrical ratings; those details remain existing listing information. Dimensions, lumen output and rated life are unconfirmed.
