Technical Any information on this lamp

Just curious if any info on this lamp I’ve had it forever. Don’t remember where it came from.
Thanks in advance love the knowledge on this site always can count on you all.

 

Vintage dashlamp. The bulb is to big and missing the cover that slips over the bulb. Replica,s are available . Sometimes fitted under the hood .

 

Wow thanks had no idea it would have a cover but makes sense.
