So I do not have pricing or warranty information about this flashlight.

The Favourlite CA-380W Spark Plug "Lite" does not have a formal name, so I'll just call it a "Spark Plug 'Lite'" or a "flashlight" on the remainder of this web page.

IMPORTANT: This flashlight has the same model as the Rocket "Lite" that I evaluated on another web page.

The Spark Plug "Lite" has a single white LED in its business-end, powered by three AG3 button cells in the body. There is also a double-headed screwdriver hidden in the white plastic "insulator".


This flashlight comes ready to use right out of the package.

Grasp the flashlight by the white portion with one hand, and turn the threaded section at the other end clockwise (as if tightening it) to get light. Turn the threaded section counterclockwise (as if loosening it) to not get light.

It comes equipped with a spring-loaded "lobster claw" type clasp on a swivel attachment, so you can easily affix it to your keychain without having to fumble with all those jingling keys.

The Spark Plug "Lite" also comes with a hidden surprise: a two-headed screwdriver (standard and phillips heads) hidden inside the white plastic "insulator". Here's a photograph to help show you:

Unscrew the very tail-end (the keychain attachment) and remove it, and tip the hidden screwdriver into your hand. There, it isn't hidden any more. :-)
You can still use the flashlight while this accessory is being used, so you can illuminate the screw or screws you're removing or installing.
When finished, just drop the screwdriver back into the flashlight, and screw the tail-end back on.

To change the batteries in this flashlight, unscrew and remove the rear portion (with the white section), throw it in the commode, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead. ;-)

Remove the three used AG3 button cells from the flashlight body, and dispose of or recycle them as you see fit. Gently tap the body, open-end down, on a table or other flat surface if necessary to remove the cells.

Insert three new AG3 button cells into the flashlight, button-end (-) negative first, and screw the flashlight back together.
One way to make this a bit easier is to stack the three button cells, flat-end down, in the palm of your hand. Then lower the flashlight body over them, then invert (flip over) your hand and the flashlight body so the opening faces up. Then screw the rear portion of the flashlight back on.
Aren't you glad you didn't flush away that rear portion now? ;-)

Measures 55mA, using my DMM's 2A scale to help minimise shunt resistance error.

Let's do that smack test now...BRB...ok, after ten whacks (five against the threaded portion of the head, and five against the plastic barrel near the key ring end) against a 30" steel rod, there was no visible damage, and the flashlight did not malfunction.

The flashlight is slightly splash-resistant, but it is not waterproof or submersible. It failed the suction test. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of siamese cat pee, slush piles, mud puddles, tubs, toilets, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found. A little rain or snow probably wouldn't hurt it though, so you need not be too concerned about using it in nasty weather.

If it fell in water and you suspect it got flooded, remove the rear portion and batteries, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater or if somebody or something peed on it, douche out the parts with fresh water before setting them out to dry. You don't want your flashlight to smell like seashells or piss when you go to use it next. Besides, salt (from seawater or urine) can't be very good for the insides.

The light produced by the Spark Plug "Lite" has a noticeable bluish tinge to it. If you took it to a group of people and then showed them the beam and asked them what color it was, many of them would holler out "WHITE!", but a few of them might holler out "LIGHT SKY BLUE!" or "WHITISH SKY BLUE!". So no, it isn't a *pure* white. I might call it an "icy bluish white".
