VW TYPE2 Late BUS WESTFALIA
144. Headlight and LED bulb
At the same time as changing the headlight bulb from HID to LED, the headlight assembly was updated from the round base bulb type to the H4 type that is currently common in Japan.
This round type bulb is written H5 or H4E, which seems to be the standard for lights on older European cars, but I haven't looked into the details.
In the original filament sphere, it was very dark because the resistance became large due to the deterioration of the wiring, so I used to a relay and made it HID, but since the power consumption was reduced to less than half with this LED conversion, that relay was also could removed.
Technological progress is amazing!
