One of the most noticeable changes when switching from the Touareg to the Canyon was the headlights. The Touareg had really nice self-leveling High Intensity Discharge (HID) headlamps. By comparison, the OEM halogens in the Canyon felt like driving with a flashlight... I found that this was a common complaint discussed on forums like ColoradoFans forums and took one of the recommendations.
It surprises me that for a high-end pickup that GM builds it with such crappy headlamps, when more modern, brighter LED headlights cost under $75 retail. GM could certainly have done better for very little difference in cost. I was also surprised to find that even aftermarket HID conversion kits are only about $250, much cheaper than the $1,200 that many manufacturers charge for upgrading to HID lights. I went with the LED for simplicity, as well as cost, since the HID lights require an external ballast, so they are a little more involved to install.
I ordered a set of Sealight X1 from Amazon, which were only $70 for both low and high beam. I ordered them on Friday morning, and they were delivered early this morning. It took about a half hour to install, and was fairly easy. The hardest part was getting under a rubber cover on passenger side, which I think directs cold air into the air filter intake.
Even in the daylight, I could tell that they were brighter, mostly due to the 6000K color temperature being bright white instead of yellow. I'm going to go for a drive tonight after dark to see how the beam pattern and throw looks.
After trying them for a few weeks, I decided that while they were brighter, that they didn't project very well, so they didn't really help me see any further down the road. At the end of February, I replaced them with the Sealight S2 series also through Amazon, and returned the X1's. The S2 do a much better job of lighting further ahead.
