Bulb list

[kenwhiteside]

Does anyone have a list of fb bulbs? Travelling to classic lemans and the French are demanding i carry spares.

Headlamp H4 60/55w (OEM fitment was sealed beam but most have upgraded to H4 requiring bulb change only).
Side R5w W5w
Tail R5w
Plate R5w
Turn P21w
Rev P21w
Fog P21w
Brk P21/5w

Hope this helps.

Or something like this https://www.amazon.co.uk/Sakura-Emergen ... PQRZDF93R1

That’s perfect.

I will check if I have sealed beam or not this eve. Here is hoping! I think they are halogen from memory and they are quite bright.

Sorry to put spoke in but I don't remember my headlights ever being sealed beam.
I'm sure I swopped out like for like H4 when the reflectors went 'Advisory' on an MOT

Aussie delivered series 3 but possibly earlier came with Koito H4 with replaceable bulbs, not sealed.

May well be that UK spec was different? Some markets were sealed beam OEM for sure. Even the Haynes manual shows swapping out a headlamp for a new one and no mention of H4 bulbs in the bulb list.

Take a look at this video from the US Original is clearly sealed beam https://youtu.be/R3e5O6QbmqY

No exterior ring on mine though, more a sandwich type retainer. Remove the entire lamp by pushing against the springs and twisting. Then remove the ring from around the lamp. Maybe just a later design?

Video is a giggle. Guy admits that he has no idea how to adjust headlights but goes and swaps them out anyway. And there is swearing,

US is definitely sealed. That is why it Haynes refers to it.

Just checked my Mazda factory manual for export RHD and it shows bulbs replacement for "except German spec" and sealed replacement for "German spec". This is the 1981 (s2) supplement.

Good info there. Always something new to learn And just when I thought I knew everything

FWIW, I'm yet to 100% confirm, but I think the RX7 headlamps with replaceable H4 bulbs are virtually identical to MX-5 Mk1 items, Mazda part no. NA1051031A

These are widely available brand new. Also made by Koito. The main difference appears to be that these are E-marked (being newer items)

There are many other applications for which 7" H4 semisealed globes are supplied by Koito as OEM eg Toyota landcruiser. I've found these brand new for a cheap price pre-fitted with Philips H4 bulbs from Toyota dealerships. However, the globe is completely flat and I believe ours are slightly curved. I don't have access to my car though so I can't check.

I have found a reference picture to NOS semi-sealed headlamps with the original Mazda part no. for the RX-7 - it is the same as early model stuff. This image was listed for a Mazda Familia though so even though it is the same part number, Koito could have changed the design by the time the RX7 came along.
