I've been thinking for awhile about the placement of LED lights in the lane markers of streets and freeways. This would be in addition to the Botts Dots and would help visibility, especially in the rain (infrequent, I know). These LED markers are already in use in crosswalks and really boost visibility. I figured that eventually they could function as lane departure warnings or to warn of lane closures, etc.

Imagine my surprise about two weeks ago when heading north on the Pasadena Freeway (110N) that the leftmost lane which enters the 5 north was lit up with white LEDs. The lights are very dense, almost a continuous line, and for night, almost blindingly bright. They last about half a mile until that sharp left for the 5. Like paint markers, the final stretch has a double row of lights. One possibly bad thing is that the markers continue straight for a short distance past the 5 turn off. If one was just following the lights, it would lead them straight into a collision with a solid object. Why don't the lights follow along with the left turning lane since that lane is for the 5 only?

A very lazy Google search didn't turn up any information.

Is this an experiment?

Are these LED lane markers in use anywhere else?

Looks like CALTRANS actually ran power lines into the lanes.

Here they are:

How much is the state of California in debt?

I'm just glad that they narrowed the exiting portion of that lane to the 5. Way to many idiots were cutting over in the dead space at the last second.

People still do it! The worst is when you are trying to get to Pasadena and in that lane and those knuckleheads come to a (almost) complete stop to make their way in at the very end.

IMO Those lights are really bright, and somewhat distracting when you are in the lane to the right of it.

I know people still do it, but the situation has improved greatly.

Nice YouTube find, Charles. The actual lights look much cooler when driving--almost like a video game. Took another look and confirmed that if one was to follow the LEDs to the end, it would lead you right into those yellow crash cans. *ouch*

So, has anyone seen these lights anywhere else? Is this a first?

First I've seen of them in the LA area. Looking at the signs and other work they are doing the area I think the eventual ideal is to let you exit from 110N to 5N from both the #1 lane and #2 lane when traffic gets really slow. Any help for this bottleneck is welcome.

The only other place I've seen little embedded lights in the street is in Laguna Beach where they have them delineating crosswalks on PCH.
