So there you have it!
The results on the road are obvious. A lot less of the generated light is refracted by the lens now that it has been polished, resulting in a much cleaner, brighter and well defined light with a sharp cutoff. Other road users will thank you too, as you’ll be giving off a lot less glare on the road.
I may follow this up with a post on machine polishing them in the near future. The finish is even better and with a lot less elbow grease too.
When doing this project, I later changed my headlight bulbs from the stock halogens to some new fangled LED numbers. I’m still testing them, but the results so far have been really impressive. Without test equipment, it is impossible to give accurate numbers but it appears that the light output has probably doubled and the colour temperature is much closer to white/blue with the new LED’s. The power consumption measured at the alternator is significantly lower with the new LED bulbs vs the old halogen too.
I may update at a later date with a post on these new bulbs.
