I've literally had four sets of LEDs in the front running lights in the past 3 years. Went from stock amber bulbs, to regular untinted bulbs, to cool white LEDs that self-destructed (quality control), to neutral white LEDs that also self-destructed (quality control), to switchback LEDs that I got tired of (didn't flash in the pattern I thought they would, I can sell them for $25 shipped if you are interested) I explain at the end of the post how they work on my car (which is how they would work on your car). Then I went to 7.5W cool white LEDs which are about 6500k-7000k, cool white bordering on blue-purple. I may also sell the 7.5W cool white LEDs too if you are interested, as I just purchased a different style switchback setup to try out.
