Light manufactures are slowly coming up to steam on this side lighting business, but I do mean slowly. So far the only front light that can be seen from the side is the Phillips Saferide, they incorporated a ring on the perimeter of the lens that glows, plus they use the same lighting pattern motorcycles use so the light is visible on the pavement to the sides of the bike. Also tail light wise is also slow, the first with adequate, actually quite good side illumination was the Cateye LD600, if you mount it vertical it could be seen extremely well from the sides this light is still around but the brightness level from the rear isn't as intense as newer models. Blackburn Mars 4 has amber side lighting but it is on the smaller side and not as intense as the Cateye ( I own that both those llights), and then the Light & Motion Vis 180 works very well too, as does the Serfas USL-TL60 the Shield.
I'm not sure why the light manufactures aren't stepping up their game on this side lighting problem, it's been known for years to exist yet they do nothing or very little. But patience as more and more companies slowly figure this out. I sometimes wonder if these lighting companies even have a cyclist working for them!! Some companies are now using flimsy mounts to fasten a rear light, why? to be cheap? That's insane, there's been reports of cyclists hitting a bump and the strap broke and the light went flying sometimes without the cyclist even knowing till they gets home and discovers they was riding around at night with no tail light!! Great going light companies.
