Replacement gauge cluster light bulbs
Whilst I'm sorting my temp gauge and have the gauge cluster on the bench, it makes sense to replace all the bulbs and I don't want to use LEDs as I want to maintain the originality and correct visual appearance, not matter how woeful.
I measured them to be about 3.6W and most of them had L36 markings on them, or 194.
I'm really struggling to find a source of these outside the US (I'm in the UK) so I must be searching incorrectly.
What is the current equivalent spec of these bulbs?

No, no, no, don't use those bulbs! They are halogen and will melt anything plastic near it. Stick with name brand bulbs like Wagner, Sylvania, etc. You don't want to replace them again. If you can't find them in your country I believe Summit Racing ships internationally

Sadly, Summit want $60 int shipping to the UK (just checked), as do most US vendors now - its ridiculous.

I replaced all the bulbs in my 1975 Corvette when I had the IP cluster dropped down. The correct replacement bulbs for the IP Cluster are Type 1895 - also verified by the 1974 Chevrolet Passenger Car Service Manual - Specifications page 29 & 1975 Chevrolet Passenger Car Service Manual Supplement - Specifications page #32. These appear to be readily available at Amazon, Walmart, bulbs.com, and all the auto parts stores (O'Reilly, Advanced Auto, Auto Zone, etc.)

They look correct, no?

Type 194 bulbs are wedge base bulbs. Type 1895 are bayonet base - twist to lock. These are two completely different bulb base styles. Both were used in 1970's Chevrolet IP Clusters. It's important to know what model year you are servicing.

Before you install al the bulbs, take the time and get some emery paper and clean the contact surface of each socket. Most of my sockets had enough build up, some of the new bulbs didn't light until I cleaned them.

Also put just a wipe of dielectric grease (non-conductive) on the terminals of the bulbs and sockets. That acts as a barrier to air/moisture making contact with the terminals so that they do not corrode as quickly. It is also a good thing for circuit board contact strips, battery terminals, etc.
