    Left and right turn signal caps
Turn Signal Extension Caps is rated 4.8 out of 5 by 4.
Rated 5 out of 5 by from Better them many other upgrades! First let me say this is without a doubt one of the best additions I have done to my ride. Stock turn signals cause you to turn your hand and lose full control for a brief time, unless you have thumbs like a gorilla. I thought since they were cheap I would just put them on. Man I can’t tell you how much improvement they have made particularly switching back and forth on multiple lanes like we have here in Atlanta. Now I will say after looking at install on instructions and my bike I decided to let my tech do it. On the new 2018’s my tech tells me it is a bit of a challenge to put them on. Took him almost 40 minutes! Now they are on they work fantastic. Just a bit of a challenge on the newer models. This small upgrade makes a huge improvement.

Rated 5 out of 5 by from A must for all bikes this product is great, had the service department install them during an oil change and it is the best thing I have done, you can reach the turn signal without having to loosen your grip or move your hand, much safer in my opinion, this will be on every bike I get from now on!!!

Rated 5 out of 5 by from Turn signal button extensions These should be standard on all models. They compensate for an obvious unsafe design that makes you loosen your grip on the throttle and/or front brake to actuate the right turn signal.

Rated 4 out of 5 by from Installation a challenge I installed these on my wife's 1200XL yesterday and they look great and function great for her tiny hands...However, the installation is very challenging as the extension portion of the switch only allows for installing them from the outside inwards. The instructions claim the switch housings do not need to be taken apart but I don't see how that is possible. Take your time and have patience is key here...
