Flashing LED + LED size question

Model Railroader General Discussion (Model Railroader)

Hi, I’m new, not a train modeler but I think this forum will have plenty tips for my pursuits in other modeling avenues. I hope you can help me with 2 main questions:

1- What is the smallest ‘gizmo’ I can purchase to allow me to create alternating flashes with 2 1.5V incandescent lights? Speed/pattern is not important.

2- What is the smallest modified or unmodified LED light that still has a semispherical cap? I’m looking to create a headlight (1.7 mm max. diameter) on the model below, and surface-mount LEDs don’t have the appropriate shape. At the moment I’m using incandescent lights. http://us.games-workshop.com/download/popup.htm?/games/40k/tau/painting/piranha/images/front.jpg

Thanks everyone!

Mouser Electronics lists a 1.9mm round subminiature led. Looks like a surface mount but has a round dome. Mouser part # 638-952SURCA2TR9 made by EVERLIGHT. Page 87 of Mouser catalog #628 www.mouser.com/everlight

Try this link http://www.miniatronics.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=6_5k they make all kinds of flashing LEDs. They also make “light bars” like the ones on top of police and other emergency vehicles that blink in sequence and different colors, Model 100-402-03 is a red 7 light chase setup - it says 12v but I power mine with a 9.6v battery & it works fine![8D]
