Must be something to that, our company changed the landing lights on our planes to alternate on / off. I had heard that flashing light was 5 times more visible than a steady one. So a flashing brake light sounds like a good investment!So far, the only LED swap I've done on my bike was the tail light, which I switched from the OEM light to a modulating LED setup. When I hit the brakes, the brake light flashes several times before staying solidly on.
Personally, I think the flashing brake light grabs the attention of the cage driver more than the eegular brake light did.
If memory serves me correctly, you need some sort of special device for your turn signals on the KLR if you want to run LEDs. Apparently the KLR expects some sort of load and without it the lights won't blink.
Someone a while back, who worked for an aviation LED company produced a LED headlight for the Gen 2 bikes. (2008+) I don't remember if that was here or ADV rider. The pictures he posted were impressive.
Then there are those flashing tail lights. Those are so very annoying when you are in staggered position and having difficulty figuring out whose tailight is whose.
So in summary, I have never put LEDs in. Too expensive for a marginal benefit IMO. Bulbs are cheap and last long enough. A 90% reduction from 5 watts is hardly worth celebrating.
Just my opinion.
At one point I bought a regular headlight that was painted blue. It was like 2 bucks on ebay and made me feel like I had a HID. So there is that.
