So is this legal or not?

[WebRuss]

Hello All

I've been looking at these replacement bulbs on aircraft spruce
http://www.aircraftspruce.com/pages/el/ledlighting_strobe/navstrobesextant.php

So reading the text in the description underneath I cannot determine if these are legal to install on my 1968 Piper Cherokee 180 D or not.

Could someone with some greater knowledge of the FAA regulations interpret for me the legality of installing these bulbs on my craft?

Regards
Russ
