DIODE DYNAMICS · 921 · HP36
Modern white light from a 921 pair.
A pair of 6000K cool-white 921 replacements with 36 LEDs arranged around the body and tip. A metal body spreads heat, and the nonpolar circuit simplifies installation in a compatible replaceable-bulb socket.
- Pair of two bulbs
- Cool White (6000K)
- 921 replacement

Light around the housing
The 36-LED layout emits around the bulb and from its end, helping a compatible lamp distribute light. Diode lists 210 lumens per bulb and a 360-degree emission pattern. The metal body helps move heat away from the LEDs.

Check the actual lamp
Match the original bulb, the lamp position and the manufacturer’s vehicle application before ordering. These are individual replacement bulbs, not complete lamp housings. They do not replace the LEDs built into a factory LED assembly.
Use the pair in a documented incandescent 921 application, such as an applicable cargo or reverse lamp. A vehicle name alone does not confirm every position. Check how many replaceable bulbs your lamp uses; this package contains two.
Install, test, then close the housing
- Switch the lighting off and let the original bulb cool before removal.
- Compare the base, retaining features and connector. Seat the replacement fully without forcing it.
- Check operation before refitting covers. For a polarity-sensitive wedge bulb, turn the power off before reversing its orientation if the supplied instructions allow it.
- Refit seals and covers, inspect the finished operation, and aim any forward-facing lamp correctly.
Bulb-out warnings or flicker require an application-specific electrical check; do not assume an anti-flicker module is included with these bulb-only pairs.
Before you fit the bulbs
Use the BTS replacement-bulb guide for the original diagrams, polarity checks and application examples. Access varies by vehicle and lamp position.
Cargo-lamp installation example
Manufacturer demonstration for 2015+ F-150 cargo and third-brake lamp access. Use only the steps and bulb position that match your truck; this HP36 pair is not a universal third-brake replacement.
Questions before ordering
Does one package contain a pair?
Yes. DD0143P includes two bulbs in Cool White (6000K). Count your lamp positions separately before ordering.
Does it replace a factory LED assembly?
No. This product replaces a specified removable incandescent bulb. An integrated factory LED lamp needs its own compatible assembly.
Are extra modules or a new housing included?
No. This listing is for the bulb pair. Any application-specific anti-flicker modules, wiring or lamp housings are separate unless expressly listed.
What warranty applies?
Diode specifies a three-year limited replacement warranty for this bulb family. Manufacturer terms, exclusions and installation requirements apply.
