dome light fade in/out

i really like how my full size truck has dome lights that fade in and out and I would like to do this in my mini truck. I have found the diagram to fade out but nothing to fade in. Any Help?

The short answer - apart from commercial offerings - is to use a PICAXE eg, the PIC 08 (or 08M or 08M2), and program it.

This circuit is simple to build.

The circuit will operate as a nice fade-in fade-out visual effects when switching your in-car lights on and off.

The fading time can be changed by adjusting the charging and discharging times of the capacitor.

To do this, adjust the values of the 10 KOhm and 4.7 MOhm resistors.

BUZ74 is a SIPMOS power transistor (Siemens MOSFET) that can handle up to 500V.

Instead of BUZ74, you can use any other power MOSFET that has a VDS value greater than 50V.

When in doubt, try it out !

ok i guess i need to mention i dont know that much about electrical diagrams (or lingo) to comprehend what you are trying to tell me. I do appreciate the assistance, but if you could break it down to little bite size bits so i can follow you, it would be much appreciated. Thank you in advance.

HWW, sell not explain, you and Oldie both fell into that one

I want one! How much?

My compliments Hotwaterwizard - that's a bluddy good circuit! Not that I've tried it, but it is certainly simpler than other discrete circuits I have seen or envisaged. However most inquiries I have seen have been for LEDs (or a mixture of LEDs and bulbs) in which case PWM is the only practical solution, and hence my PICAXE suggestion where a $5 PICAXE 08 plus its 2 programming resistors, input resistors etc, 5V regulator, output MOSFET (or transistor) and "simple" programming can do any dimming rate with whatever delays and trigger(s). But I reckon one day I'll build that circuit, though I'll probably add an input resistor (1k?) to limit input current if using a grounded switch that feeds some other +12V circuit or load.
