[QUOTE="olderndirtmom, post: 1237531, member: 77254"] Question to you law enforcement types and traffic engineers. What causes traffic signals to change for alternate traffic, particularly late at night? To be even more specific, some friends of mine are arguing the "flash your brights" method of getting signals to change faster versus the electromagnet under the pavement. One swears by the "flash your brights". The other believes that the electromagnet thing is a ruse to get people to buy a gadget they don't need, since the only information he could cull on the subject was by a company selling such a gadget. I dutifully reported what I learned in motorcycle licensing school on the subject (electro magnet buried under asphalt). I also reported what I was instructed to do when my cycle couldn't get the signal to change (run the light)...But I wonder what you DRN sages know about the "flash your brights" thing that has been circulating since I was a child (shortly after electricity was invented) and the history of the technologies governing signal changing in the wee hours. Any of you have inside knowledge on this subject, and the urban legends (and various snake oils) surrounding it? [/QUOTE]
