Interior Light Fader

Has anyone ever bought one of those Interior Light Faders out of the LMC Catalog? In there new catalog they are on page 152 bottom right hand corner. Just wanted to know if they really work. Not cheap. $34.95 + ride.

About $5 in parts and some work on your part and you can make one.

Now you are going to have to do better than that. What parts, where do you get them and how? I am all for that if you can answer these questions. Sounds good to me.

PM me and I'll build one for you. I bet I have the parts in my spare parts box. (Electrical engineers have these sorts of things...) :-)

That would be a cool mod. How would you move the switch to the ground side? The switches in our trucks ground the light circuit which has 12v all the time. It could be done with a relay, but is there a more elegant way?

I've revised NeC*'s OpAMP schematic to be activated based on close-to-ground door switch. I'm not sure the diode (D1) is required to protect the CMOS inverter's output when the capacitor (C1) is discharging (driving the OpAMP to dim the dome light). Maybe, NeC* can verify the circuit (before it's 'breadboarded').

BTW, the potentimeter (VR1) is used to control how long the light fades and the potentimeter (VR2) controls the intensity of the light.
