The bulb is a halogen car bulb. Take it to your local auto parts store like Canadian Tire.

Vector is a part of the Black and Decker company and almost all items with that name are made in China.

I assume you tried to Google the model number for "bulb" or "lamp"

Go to your local Batteries + Bulbs

If the bulb is an H3 55W 6V bulb, go here - http://www.doitbest.com/Halogen+bulbs-Dorcy+International-model-41-1680-doitbest-sku-804678.dib

You can order one from Black and Decker, they bought Vector in 2006, here is the link;

Check the contacts going to the batteries. The negative contact is
going the flashlight body. While the other starts at the center of the
bulb socket that goes to the switch and finally to the positive terminal
of the battery. Get it done and send an e-mail .

It takes a H3 bulb which is available at most parts stores and Wal*Mart stores in the automotive section.

The bulb you are looking for to fit these vector spot lights is an automotive bulb, and H3 with a PK22s base. They come with a cable and a nickle size disk at the base of the bulb. They come in several wattages, eg 55w and 100w. Try the "bulbs.com" website, in their search box type "H3 PK22s" and you will see they have a variety of wattages and voltages. Be sure you buy a 12V for these spot lights. They come with a cable and nickle size disk at the base of the bulb. Hope this helps. From Uncle Ray
