At last a modern H4 bulb

This adapter worked exactly as advertised, in just a couple of minutes I had ditched the old tungsten bulb and installed a new H4 bulb. Couldn’t be happier, great product and great service, what’s not to like 👍

Had to modify the bulb clips

These are great but they put the rear edge of the bulb base nearly 5mm further out so my original bulb clips wouldn't fold over the extra height. I couldn't make the originals work but fortunately had some others that I was able to bend so they did fit and hold the bulb in place. Apart from this, they're just the job!

We are looking at a permanent solution to this not common issue. Thank you for your feedback.

Does exactly what it is supposed to do!

Excellent product. First class advice and service.

Bart Beeman
Well made and works perfect

Over the years can't count how many filament bulbs have failed on my 1977 Bonneville Silver Jubilee. Used to carry a spare, which was dicey due to size and frailty.

Now that LED headlights are brighter and much more rugged I'm upgrading all my toys.

Much more availability with H4 bulbs and this adapter is just the ticket!
