The hardest part will be getting LED's that are not to bright or to dim, which is a personal thing i guess. FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

I think your right, trial and error to match what's already fitted. Modern LED's are always very bright even with a reduced voltage. It might be easier to change the resistance values of the dimming switch. Well iv found something to occupy myself today, the MOT on my other car expires tomorrow so off for a test I go |

No I'd actually leave the yellow ones (suspension/heated seats) I mean anything that lights up green inside once the external lights are turned on. That said do they already emit white but each switch has a green diffuser? |

I'll plug a spare pcb in and investigate further. |

I think you'll find they are actually green LED's - not white ones with a diffuser

I think they are green too, that's perfect. I'll have a look on RAVE for schematics regarding that control module. In theory it should still be resistance dependent. I know a good electronics company that could identify the values of the green LEDs and offer a similar matched value. |

Someone on here did change all their dash leds to white when they had their pixels done. Do a search on "pixels", there were photos too .

I have been thinking about this for quite a long time too, the dash is the easyest bit to do i think, but the touch screen will be the worst!

I noticed the other night that the left hand temp dial is a fair bit dimmer that the right hand side, so I wonder if this is repairable by replacing the control board with the LEDs on it? Got - 2017 SDV8 Autobiography in Loire Blue

Typically, the resistance of the "dimmer" is used in the PWM circuit to determine pulse width. You don't dim LEDs using a resistor, you dim them by sending pulses of full voltage; the wider the pulses, the brighter the LED appears. Pulse Width Modulation. Otherwise, you have to dump the heat generated by the variable resistor. Old school. Jim 2000 NAS HSE 2005 NAS HSE |
