T4 Interior Light Upgrade

[jets]

My camper is based on the transporter so has the basic interior light. While wandering around the wreckers[U-pull-it] I noticed a couple of Seat Cordobas. The interior lights looked the same size as my van but had the addition of a map reading light.
I carefully removed them & noticed the printed circuit board with extensive componentry. I figured they must have delayed turn off.
I payed $6 each[new VW price $200] so figured not much demand for them.
The wiring plug in my van was identical, so it was a 2 minute job to install. The light could be installed with the map reader for the driver if you travel alone.



Now there is a bit of a trap,both lamps were removed from '95 Seat with the same part no ILO 947 105B but they are different lengths.
One was made in Spain[didn't recognize the brand], the other[the one that fitted] was Hella brand made in Germany.



The lamp that is longer & fits is the one in the foreground.

I found the time delay was too short for me so I asked a close friend who is an electronics Guru how hard would it be to increase it.
Very easy he said. The 25 micro farad electrolytic condensor was replaced with a 100 mf which increased the time to 23 secs.
While we are at it I could change the festoon globe for an LED he said. These were only a couple of dollars on Ebay from china & two were soldered in parallel. There is room for a third if you want even more light. He suggested, in retrospect it would have been nicer in warm white rather than in daylight.
