I took my caravan for a short drive after installation. They look awesome when you look at the car. Crisp, white with a bluish tinge.. They're pretty bright, when you compare them to the stock halogens against a wall right in front of the car, led headlight looks stronger, as you can see in the picture. when driving around, the light beam just seems weak a little. Later I found that it is not because lighting is being weaker... the problem is that anything over 6000K-7000K in color will lack "darkness piercing" ability, meaning they really don't light up the road very usefully. For the best penetration in the darkness, you want between 4000k-5000k (there'll be people that argue that sunlight is 5300k so that must be the best)
These bulbs are totally plug and play, I means they don’t need resistors to increase the working power. They don’t have cooling fans, I don’t need to worry about fans broken.
