Maybe people are flashing to warn you of a speed trap ahead. That is a very common but illegal reason for headlight flashing. Most of these "warnings" are pointless as it is not always clear who it is being directed toward.
....or what its being directed towards.
No, its definitely because of the DRL's, like I said, 10 flashes in the last month, in broad daylight, on town roads, with no speed trap afterwards.
Didnt have that many flashes before.
I will admit they could look like my foglights, because it is a bulb not LED's, and its in the foglight housing, not the headlight housing or eleswhere like most.
Here is what I mean;
As you can see, single housing, DRL on the left (on) Foglight on the right (off).
Cant people just ignore it, rather than trying to make a point of it? The only time really I flash someone is if they forget to put their lights on at night.
