I love LEDs on bikes. I love the ones on my bike and my husband's bike. Would I/We do it again? No!!!!!!!!!!!!!
Do they look good? Yes!
Do you use them enough for the cost? No!
And now - after a couple of years, my husband's LEDs have moved around after different service works and are not as well placed originally - but this of course is overcomable.
Mine on the other hand, some where in and amongst them, there is a problem that caused my battery to die, and need early replacement. No sooner replaced the battery than the new one went dead. Have narrowed it down that the LEDs somewhere, somehow are a problem and so are now disconnected. Worth the cost? I think not.
JMHO of course, you do as you wish. Again, do I like them? Yes, just would not do it again.
