Diode Dynamics · One 29 mm festoon bulb
A compact festoon upgrade in five colour choices.
Replace one matching 29 mm incandescent festoon with the HP6 LED bulb. Choose Cool White, Warm White, Blue, Red or Amber. The 130-lumen manufacturer model rating and diffusing lens make this a focused interior-light upgrade without buying a complete conversion kit.
Confirm the fit first
For a matching 29 mm festoon holder with adequate clearance. Diode lists the 2017–2023 Tacoma dome location, but explicitly asks owners to check the original bulb size because some trucks use a different length. Do not substitute this for a measured 31 mm bulb.
Choose your configuration
Cool White · 6000K
A crisp white interior appearance.
Warm White · 3000K
A warmer white tone closer to the original interior character.

Installation planning
Measure and compare the original bulb before fitting. Use a non-marring trim tool at the lamp's release point, allow the original bulb to cool, and test the LED before refitting the lens. If it does not illuminate, switch off the light and reverse its orientation. The holder must grip the bulb securely without forcing it.

Questions before ordering
Is 29 mm guaranteed by my truck's model year?
No. The manufacturer lists a 2017–2023 Tacoma application with an explicit original-size check. Inspect your own dome bulb.
Can I buy a complete interior set instead?
Yes. The complete Tacoma kit is linked below, but it also supplies a 29 mm dome bulb. Check the same fitment point before ordering.
Is the SMD12 option another 29 mm festoon?
No. SMD12 is a separate rectangular panel using a socket adapter and requires enough room inside the lamp.
Do I receive two bulbs?
No. This listing is one bulb.
