Okay, time for my bi-annual headlight modulator post.
I have one. I think using it when conditions warrant they're a great thing. All the time perhaps you should take the cage.
So, what are those conditions?
1: Nobody in front of you (car or bike) for at least a quarter mile in your lane.
2: Two lane rural highway where traffic is heavy enough to warrant the fear of somebody pulling out on you. But not so heavy that anybody who pulls out would be a SERIOUS *******.
3: Medium to light traffic in an urban environment. Heavier traffic and you should be using the cars as blockers.
Thats it. The only other times I use it is to ACTIVELY be noticed. Somebody waiting to make a left in front of me, especially if their front wheels are already turned. Somebody waiting to pull out of driveway. Getting somebody to pull over
But those are flip them on for a few seconds, then off.
Otherwise, your just pissing people off unnecessarily.
My pet peeve with them is the times I want to use them the most - two lane, oncoming traffic is being led by a transport with a line of cars behind waiting to pass. You flip them on and see the truck driver go ballistic flashing his lights at you. I've had them do that AND BLAST the air horns as I go past. Truckers have a thankless job, and the majority of them are VERY safe drivers in a bad situation - unfortunately, they have no control over the idjits behind them.
If I accidentally trigger them in town it's only for a few minutes because guaranteed within 3 or 4 red lights somebody will pull up beside me and TELL ME my lights are 'broken!' Ya, they work, but I have enough to worry about then pissing off EVERYBODY in front of me when not required. Think about the danger before using them. They're great, but if you flash enough people, someday they'll be made illegal.
