This is my guide to repairing the Hella Celis Halo Rings, when the green voltage regulators blow!
This is a common fault on these headlights, especially after fitting HID kits.
Step 1 - Parts.
After hours of research, I decided to order the parts I required from a company in Canada called Luxeon Star.
Package from Canada!
- 2 x 350mA Power Puck DC Driver - £14.33 each.
- 4 x Cool White 6500K LED's (optional) - £7.34 each.
- 1 x Thermal Adhesive Pads (optional) - £4.79.
The LED's & the thermal pads are optional, depending if you want to replace the LEDs while you are carrying out the repair.
Step 2 - Strip Headlights.
Remove both headlights & strip out the old green voltage regulators & all the bulbs, along with the LEDs if replacing.
If replacing the LEDs you will need to remove them. They are 4 LED's in total, which are attached to small heatsinks. Note: the bolts for the heatsinks are difficult to get at, as the headlight lens slightly covers the edge of the bolt. A small angled torx bit is required for ease.
Old Parts Vs New Parts.
The new LED's are much smaller, but brighter & will need attaching to the heatsinks with the adhesive thermal pads.
The new Voltage Regulators are about the same in size, but more heavier duty.
Step 3 - Repair.
If replacing LED's, then remove the wiring loom to the LED's, remembering how the loom was routed. I wanted to solder every connection, as the voltage regulators rely on a very good Earth connection.
I drew a very scrappy diagram to work out where everything went.
Then re-assembled everything.
Re-assembled & routed wiring through headlights & zip tied all loose wires. Drilled a new hole for the new voltage regulator, the new ones are slightly bigger.
Step 4 - Completed.
Ready to re-assemble.
Step 5 - Trial Run.
LED's are brighter, but Celis rings still not as white as they were when new. Still, at least they work!
If anyone has any questions, please ask! Hope this helps some of you Hella Celis owners!
