Is this a relay mod?

This has always been on my Duster since I bought it. It clicks when you go from low beam to high beam. One wire runs directly to battery positive. A previous owner have taped all the electrical wiring together and since everything works I have never touched it. So, Im guesing some one has relayed the high beam right? I know I just guess, since I have not followed the cables. But it's not a stock thing right? Sorry for the bad picture.

Hi trebor75. It looks like a headlight relay that was installed when the last owner put in some quartz or halogen bulbs. In the eighties it was common to upgrade the headlamps but a relay was required for that early bulb technology. Looks exactly like the one I had!
