Yes Wvg-ca tiny SMD LEDS. I think a 1/8 inch hole has to be drilled. I installed one. I think I used a that size drill. I'll check tomorrow. I'm going to use them in my yards and stations. They look great.
Be aware the LEDS used in the lamps are of the SMD 3v type. I think if you ask for a free resistors in the note part of the order the seller ship them for free. I have two 3v power supplies so I didn't need any resistors.
