This is the second set of these lights I have purchased. 1st set were included in the sale of a previous bike. I don't like the halogen bulbs that come with these lights...they run much too hot and use way too much current. I have changed the halogen for H3 LED. Solves both problems in one go, looks much better and the beam is much brighter too. Also, I am more visible to oncoming traffic, hence the reason for fitting them in the first place. I also found the handlebar switch to be unsuitable for me so I purchased a more robust unit from e.bay.
Hope this review is helpful.
