Railhead brand blue light for Carmen, under GCOR 5.13, I have 2 brand new old stock, only opened to test, uses one D battery, it has a double flash with a short half second off and repeat. Simple on/off switch with led battery indicator light, you can't change the flash rate it's factory set
Has a strong yet removable magnetic base. As you can see it's about the size of a pop can, these can be used on the full size as they are FRA compliant, yet small enough to enjoy in 1/8th scale or bigger.

I have 2 available for $35 each plus $10 to ship, yes I will combine shipping if your buying multiple items just please let me know.
I generally ship USPS, if you prefer another carrier please let me know, there ups and FedEx where I live as well.

Keep in mind the battery is NOT included, but you can get a 4 pack at Walmart for about 5 bucks, One will last all weekend at a meet. The clip on the back is handy to clip onto 1/8th scale equipment as well.
(The light in photo is my personal light. You will receive a brand new light, this photo is for reference)
