Each circuit board has an array of LEDs that convey a message. One circuit board can be positioned in the end cavity portion in at least two different orientations. The end portion of the cavity and the one circuit board are preferably octagonal in shape to accommodate several orientations of a circuit board having arrays of LEDs arranged in symbols such as an arrow or a stop sign.

Why it's free to use
- Filed October 17, 2002 and granted September 20, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 17, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 17, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
