What is the consensus on what is better to simulate headlights on tanks, WWII vintage.

Clearly bright white/ blue leds aren't correct as I'd imagine the lamps of the era tended to be
yellowish. Yellow leds would be too yellow.

So does that leave grain of wheat bulbs? I believe that's what Tamiya used in their Pershing and probably
others.

I read parts of a thread here where the author mentioned 1.8mm yellow leds but still they see too yellow
then I haven't tried them.

What is everyone's thoughts on this?
