When the idea came to use a car headlight as street lighting, the question immediately arose about the power supply for such lighting.
Using a “original” 12-volt light bulb turned out to be problematic - the transformer does not fit inside the headlight! There was no desire to separate a weatherproof housing for this purpose and lead large cross-section wires from it to the headlight.
The way out of this situation was the use of compact halogen lamps with a voltage of 220 volts. Lamps with a power of 35 and 50 W were found on sale. I heard about 75 W, but couldn't find it. I used both types found and they work successfully.
All that remained was to come up with a reliable way to mount it in the headlight, allowing you to replace a failed lamp without much difficulty.
Let's start by “disassembling” the standard 12-volt lamp in order to remove the fastening elements.
The lamp consists of the lamp itself and the mounting “skirt” connected by soldering.
We separate the lamp from the skirt, thoroughly warming up the soldering area on any available equipment, in our case it is a gas stove.
Then we cut out a piece from the foil PCB, mark it according to the size of the light bulb legs, drill, cut, solder around the perimeter and in the end we get the following:
The search for mounts for lamp legs led to a flea market. The “2RM” (female) pin connector was ideal for our purpose.
Try it, try it on, you’ll definitely find something.
Insert and solder the “leg holders”
That's all - the lamp is ready to be installed in the headlight
Everything looks like this when assembled:
