A tiny flashlight on your key chain is always with you and is very useful. Opening the case and putting in a label turns it into an interesting memento.
The electric service fails and you are in the dark. A flashlight - any flashlight - could be a lifesaver. I carry a tiny flashlight on my key chain and have used it dozens of times to find my way in the dark. It also is useful to locate the keyhole for a lock or a vitamin pill that rolled under the sofa. I even have one on my pajamas drawstring for midnight trips to the bathroom. I paid $20 (USD) for my first one 9 years ago. When I found a inexpensive source, with an average cost of $0.50 (USD), I bought them for my family and friends. I found that it was easy to add personalized logos and give them as useful mementos, such as wedding trinkets; church, school or military unit souvenirs; or business cards.
Step 1: Materials
1. Flashlights. Available in bags of 10 at http://www.dealextreme.com/. (DX SKU 1100) Each has a bright LED and 2 long-lasting CR2016 button batteries.
2. Jewelers phillips screwdriver
3. Round Labels, 3/4" (.90 cm) Avery 5472 or equivalent. You can use white or colored labels, but the printing on white labels shows up better than on colored labels.
4. Optional: A battery powered screwdriver will save wrist and finger wear if you are dong a lot of flashlights. Many on-line tool suppliers carry these. For example, www.homedepot.co/ has General Tools Power Precision Screwdriver, Model # 500, Internet # 202025658.
5. Optional: Rubber mat as work surface
6. Optional: Magnets. One or 2 small magnets taped underneath your work surface can hold the tiny screws as you remove them. If you don't have one on hand, www.dealextreme.com/ can provide (DX SKU 4248).
Step 2: Prepare Labels
You can get the artwork for your flashlights by downloading clip art, photos, logos, etc. Look for bold designs. Fine print is not easy to read through the cloudy plastic of the flashlight. After selecting the artwork, design the labels. Some word processing programs come with built-in templates for labels. Avery (www.Avery.com) has a template for this label that you can download for Macintosh or Microsoft Word. Avery also has some that you can use on-line. Design and print your labels.
Step 3: Install the Label
Remove the screws, open the case of the flashlight, and put in the label. You can orient the label to be left handed, right handed or vertical. Grid lines can help you line up the label. Press the label firmly over the LED wire, onto the battery, to keep it from shifting. Put the cover back on.
I've added a second label to a few flashlights. This label goes on the other side of the flashlight, the switch side, and must be trimmed to fit. It is not worth the bother.
