Quoted from nipper2u:3. Is an LED kit like that from PinballBulbs.com the best way to accomplish this?
I tend to buy bulk bags of Comet twin 2835 Sunlight whites with frosted domes - they look good under all inserts. 75% wedge, 25% bayonet.
Red LEDs do look slightly better under Red inserts, but i have spent far too long drawing up lists of the exact bulbs i wanted per game and i'll never get that time back. Ever. Some types might be out of stock, or wrong, then i need to re-order.
Just buy a load!
Plus if all bulbs are the same colour they'll be the same brightness too (hint: avoid Yellow LEDs).
Love the OCD products.
