Rhombus turn signals are waterproof and feature LED lighting and a "Longlife-Protection-Guard-Electronics" circuit. Rhombus lights are EU approved for use on motorcycles for front and rear use. Rhombus Extreme lights are EU approved for use on quads, cars and trailers, as well as for motorcycles, even fitted in a distance of only 2cm from the head light! There is even a "Stealth" version with a black housing and the lens dark as the night but super bright when working. Installation of LED type turn signals requires -except for models with a CAN-Bus system-, the use of an electronic turn signal flasher unit such as the ZPN 237304 or two Kellermann in-line resistors ZPN 742046 to retain the original flashing sequence. Resistors as well as turn signals are sold each.

Note: Replacing the stock turn signals with turn signals that draw less Amps, such as LED turn signals, requires the separate purchase of a Load Equalizer or replacement of the stock turn signal relay with an electronic turn signal flasher, such as ZPN237304. CAN-Bus (HD-Link) equipped 2011 to present Softail, 2012-2017 Dyna, 2014 to present Sportster and Touring do not require a Load Equalizer when LED turn signal inserts are used, as the blinking speed can be adjusted.
