Thank you for writing to me about 4300k halogen headlights.

In this letter, I would like to explain to you 4000k halogen headlights in brief.

Since 2013, my factory started to produce 4000k halogen headlights.

All of our 4000k halogen headlights are using “Anti-uv quartz glasses” and also put enough halogen gas inside.

So the life time of our 4000k halogen headlights is 3-5 times as long as others.

At recent years, my factory also developping 4000k led headlights.

If you can give our 4000k halogen headlights a chance, I am sure you must win in your market.
