Just fitted a pair of LED H1 type bulbs for my Fulvia inner headlamps, so I thought I’d give a couple of tips to anyone who might be thinking of doing the same.
The bulbs were bought from:
https://www.hids-direct.co.uk/h1-led-headlight-front-fog-light-bulbs-9-32v-4000lm-csp-2021-6500k-pack-of-2/They look identical to the ones on the Pieces Fulvia website, although it’s quite a lot cheaper to source them in the UK.
The job is very straightforward, however the bendy spring steel H1 bulb retainers will have to be modified or more likely new ones made up with 150mm of about 1mm diameter steel bent to the appropriate shape with a pair of pliers.
The bulbs simply fit into the black “bucket” housings fine with the extra length of the base not a problem.
The main reason for the LEDs is current drain. I have a pair of period slimline Cibie Iode 45 driving lamps and the current drain of getting on for 28 amps for 6 lights was close the the alternator output, and that’s before various other lights and the ignition system, so LEDs are a sensible change.
I couldn’t find any LED H1s that would fit the Cibies which would have been the easiest option, hence fitting them into the inner Fulvia headlamps.
