We found these great little light bulbs with other vintage model railroad supplies and thought they might just be what you need for your next altered art project. They are new old stock, never having been used and are in their original packaging.
These are marked:
No. 437 ONE Pea Bulb - 6" Leads WHITE 12V-15V PERFECT .75
On the back, the package reads:
MADE IN HONG KONG THE PERFECT PARTS CO. BALTIMORE, MARYLAND 21224
Because these are in their original packaging, we've not tested them. These are vintage, so please use caution.
