A clean halo accent around your retrofit
Diode Dynamics · 90mm pair · 2014–2021 Toyota 4Runner
Add a uniform illuminated ring inside a custom headlight build. Choose fixed White, fixed Red, or White/Amber Switchback. These are retrofit components: the headlights must be opened, the rings mounted and wired, then the housings resealed.
Choose the output you want
| Choice | SKU | Function |
|---|---|---|
| White (6000K) | DD2074 | Fixed Cool White with dimming inputs |
| Red | DD2050 | Fixed Red with dimming inputs |
| Switchback | DD2062 | White running light and Amber signal input |
Only Switchback changes from white to amber. The Red option is a custom accent colour; confirm the permitted use before using coloured lighting on public roads.
90mm mounting space is required
Diode Dynamics lists this pair for 2014–2021 4Runner headlight retrofits. Each ring has a 90mm outside diameter, 74mm inside diameter and 4.5mm height. Confirm clearance in your actual housing before opening it, particularly with aftermarket headlights.
This is not a replacement bulb or a complete headlight. Custom mounting, electrical connections and opening/resealing the headlamp are required. This application does not extend to 2022–2024 or 2025+ without separate fitment evidence.
Use the matching supplied drivers
Each pair includes two drivers. Always connect each ring to its driver before connecting the input pigtail to vehicle power. Never power the ring directly from 12V.
| Choice | Driver | When low and high inputs are both powered |
|---|---|---|
| White | AC0044 · Singlecolor Type H Low | Low output takes priority |
| Red | AC0057 · Singlecolor Type H High | High output takes priority |
| Switchback | AC0029 · Switchback Type SF Low | Low white output takes priority; Amber signal overrides |

Plan the retrofit
Can I install these without opening the headlight?
No. The rings mount inside the lamp. Professional installation is recommended for opening, mounting and resealing the housings.
Is Amber-only available?
This listing offers White, Red and White/Amber Switchback. Choose Switchback if you want an amber signal function with white running light.
Do wire colours match the light output?
No. White and red input wires select lower or higher output. The selected ring determines the emitted colour; only the Switchback ring provides white and amber.
Can I use these as a full headlight beam?
No. They are accent rings, separate from the headlight low and high beams.
