My personal view is that there is a deep flaw with this forum, in that there is no area free from commercial sales contributions, wanted or otherwise. Even this thread had been purloined, perhaps with the best intent, as advertising and promotion for a particular bike shop.

The reason I spend more time contributing on ES, rather than here (apart from the obvious fact that ES is many times larger as an ebike forum, meaning far more interesting discussions) is because ES has a very rigid policy on only allowing commercial content in one specific area of the forum. Discussions there don't get derailed by dealers getting a bit of free advertising, if they tried it they'd get warned then banned on a second offence.

As a final point, getting back to the thread topic, I should add that these laser lights do not contain a laser pointer at all. They don't project a focussed, parallel, beam of light, in fact they do the opposite, in that the optics are designed to project a wide angle fan of light downwards at the road either side of the bike.

If they did contain beam collimating optics, such that they could project a near-parallel focussed beam like a laser pointer, then I'd be the first to suggest that they might not be safe or sensible. To compare them to a laser pointer, however, seems to be scaremongering, given the clear difference in the way these lights have been designed.

I'm personally looking forward to when Jerry has received his and is able to give us his thoughts. I have doubts as to whether the lines they project on to the road will be particularly visible in practice, but if they are, and if they tend to make motorists give a bike a bit more room when overtaking, then they would seem to be a good idea, one that should be encouraged and developed, rather than likened to the sort of thing a miscreant might misuse. If they do work, but aren't yet approved to a suitable standard for use within the EU, then perhaps the manufacturers should be encouraged to try and seek approval.

I've seen a review on this some while ago which felt the idea was not useful in practice. The reviewer's finding was that car headlights swamped out the laser effect on the road, leaving the laser lines invisible to traffic so making it's use ineffective.

Yes interesting point flecc. We will see.

As I said they are not that expensive so just a bit of fun. I seem to never have enough lights as I end up giving them to family and relatives as I like to know they are riding well lit up.

In fact they also keep giving me their regular bikes more and more to fix/service lol

I use a Hope District - the brightest rear light I have ever seen and cars certainly notice me day and night.

Once again sorry, by commenting I was merely pointing out a really good light that I have come across that may be useful to some of you guys.

We've discussed the issue of trade posts a number of times previously Martin and the majority view is that we find them useful and wish them to continue. Most of us welcome the help that suppliers give with problems on their products and also like any announcements they have on products they are introducing. Therefore I doubt most will find fault with you posting.

There are a minority who don't like trade posts in threads as Jeremy has rightly observed above when comparing this forum with Endless Sphere. However, this forum is different in nature to that one, this one much more consumer focussed, the ES forum more constructor and technical enthusiast biased. I think it's best they remain different and continue to serve different purposes to suit all tastes.

@Petersfield cycles. I personally do not feel that you acted unreasonably. Full marks on your arrangement with the local police. The offenders are getting a good deal, as they spend less than the fine, and end up with lights. In these difficult times, businessmen who are backwards at coming forwards soon become ex- businessmen. Having said that, if I rode at night, and might still be tempted to buy a laser light.

Was with the neighbor when I got home :p

I must admit the novelty of the "laser lines" is really quite impressive. More so in that they are static or can flash on and off. I think static will be more effective. Also I thought you had to ride to get the line effect but the line is projected onto the floor. Spacing/length of the lines depends on the height of the light off the floor, which on the Brompton will be pretty variable either on the seat post or the lower rear frame. The actual light (five leds) again is static, blinking or rotating through all five.

Build quality is reasonable a little brittle plastic feeling, but ok. Not sure how it would fair if dropped onto a hard surface. I hear there are other copies on the market that are very cheaply made, according to the ebay seller anyway. Clip fitting seems effective and secure.

My only criticism so far would be that you have to take three little screws out the back to fit the battery. I already dropped one on the carpet and am still looking for it :rolleyes:

Comes with a set of cheap batteries though :)

I will report back tomorrow after my commute home. Novelty factor will be interesting given I have not seen anyone cycling in Cambridge with one yet.

Give a man a fish, etc.
Teach him to brew his own beer, on the other hand
and he'll never get off his sofa.

Ok fitted to the bike no problem. Everyone that sees it wants one. At work I have been giving out the ebay link to loads of bike users.

Thoughts so far in use:

1. Very distracting as I keep wanting to look down at the lines :p
2. On the Brompton the pedals going round do interrupt the lines but quite effective as they are then drawn shorter and longer alternatively.
3. Its a little bulky on the Brompton.

I have ordered one of the smaller 3 LED ones now as well.

I'm interested to know if the lines remain visible in good lighting or with a following car headlamp beam on the road where the lines are. I suppose you'd need an observer to report that, especially to see if a car driver is aware of the lines when they are using the headlights.

Flecc, I did ride on a main road a little and the lines remained very visible even in well lit areas.

As you say I would need the comments from a car driver to establish how effective they are.

I like them and now have both the larger and smaller models fitted on each of my Bromptons.

It will be interesting to see if the trend increases as per your link.
