DTRL's have been the topic of in depth study for probably thirty years or more... I call it the Volvo effect... as their decision to make headlamps hard wired probably got the ball rolling.....
Thirty-Forty years or research..... and the Verdict is STILL 'out'!!!!
What does that tell you?
Quote: | the INVISIBLE biker!
The Topic of 'Conspicuity', Hi-Vis gear and the SMIDSY; Sorry Mate I Didn't See You. A look at WHY SMIDSY accidents occur in the fist place; then what its suggested you can do to help avoid them; 'Conspicuity' aids, Day-Time-Running-Lights (DTRLs), Hi-Vis, or high-visibility clothing, and things like that. THEN whether they ACTUALLY might 'Help', as well as some of the contention over 'compulsory' Conspicuity aids. |
My thoughts and a little empirical on the topic... personally I don't think that DTRL's do much if anything to make you more conspiciouse.. to which many say "Yeah, but it cant hurt.. so might help.. use'em!" which, I think, if you did down a little isn't so true. A bright DTRL can 'glare' and make you less conspiciouse, just adding to what is already a feild of fun-fare lamps everything clamouring for folks attension, from shop signs, advertising hoardings, kids trainers, flashing dog collars, etc etc etc.... and as the ambient lighting dimms, with weather or twi-light, the situation just gets worse, with DTRL's just 'lost' in the sea of neon.....
My p[ersonal thoughts is that a low wattage side-light just making the headlamp bowl glow, probably gives about as much conspicuity as anything, without the glare, and gives observers better chance to work out what the lamp actually is... and more, recognise its a biker, more still, remember that they probably dont want to SMIDSY said biker.... and even more... MAYBE just maybe do something different NOT to SMIDSY the biker.....
Which is to hang a lot of monkets off the tree way beyond turning the lamp on.... to which, turning the lamp on, is but small part, and if they do or dont see lamp, you are in a world of trouble before you begin...
So its not about whether you put the lamps on, or not, its about riding defensively, NOT assuming that cos you have a lamp on, or are wearing HiVis, or have used an indicator or anything that they will have taken a blind bit of notice, or will do the right thing, or will do anything at all to watch oyt for your arse... only you can be relied on to do that... So?
Dont ride like a tit to start with? No make danger, not going to hurt you.
See danger... dontr go there.... keep your eyes open and dont expect ANY bugger to watch out for your arse, they likely have a million other things on thier mind, all far higher up thier list of priorites.
In danger? Well, get the fcuck out of it! why were you there in the first place, you fool!? B rakes steerrng, DONT PANIC, keep your cool, and control the situation you have got yourself into.. so you dont get hurt.
Last line of defence? Oh dear this gonna hurt.... nothing you can do, its all to late... hope that the hat and the leathers may cusion the blow a bit before you hit something hard and unyeilding.... but it gonna hurt.. and would a bludy light-bulbv have helped?
When it comes to that, a whole list of things have gone wrong in the chain of events, of which a DTRL is but one, tiny influence, that really has so little and shouldn't be relied on... like road surface, tyres, brakes, or SMIDY man to do what the Highway Code says he should.....
So, the answer is? Personally... I tend to ride on just sidelights, so not to add to the confusion, or dazzle other traffic..... otherwise... I use my eyes, I use my instincts and rely on thirty odd years of doing this schitt for that 'sixth sense' to try not get into trouble..... and put my faith in that.... not the ruddy headlamnp..... and STILL smidy's try and kill me.......
It makes small odds in the greater scheme of anything... so lights or no lights.. do whatever makes you feel most comfy... but dont put your faith or your life in ANY thing to keep you 'safe'.... it dont... and only thing that can in anyway help is a little common cocum and boring being sensible, and keeping your own eyes open! ____________________ My Webby'Tef's-tQ, loads of stuff about my bikes, my Land-Rovers, and the stuff I do with them!

No they don't.
Specifically if you have your lights on and the engine running you battery will be fully charged all the time. Your alternator gives out way more than your lights use.
Also, lead acid batteries have a cyclic life. While they will last for a good while fully charged, they will not if discharged and recharged. The obvious case are leisure batteries, which are designed for that sort of use and have a specific cyclic life. Starter batteries are not designed for a cyclic existence.

"Position" lights on the Enfield, because why not? It lets people know that you're riding an Enfield, so that they can make allowances for your braking distances.

Lights are a mixed blessing. They can make it much harder to judge distance. SOmetimes all you see is an approaching point of light becoming slowly bigger and unless it moves oddly, isn't immediately recognizable as a motorcycle (hence why many riders will do a slight weave as they approach a joining junction).
If there are a lot of lights in the background, a motorcycle can get "lost" in the clutter.
If the background is particularly bright, a light can actually camoflage you.
Since all new vehicles now have permanantly on daytime running lights, the advantages of using them are greatly diminished. Same goes for yellow hi-viz, every fucker is wearing it now so it gets filtered out, or worse, labelled as "slow miving". One of the reasons for me wearing orange hi viz.
I make a decision on if I'm having mine on or off based on the light conditions , traffic volume and background. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”
