The LED indicator bulbs compatible flasher module plugs in and installs like the OEM module, but would prevent hyperblink even if all indicator bulbs are changed to LEDs.
The functional advanage of LEDs are lower current consumption which, with all LED setup can be reduced from 94W (4x21+2x5) to 10-12W if LEDs are used. The LEDs bulbs last considerably longer.
The Jass Performance Flasher Modules come with buzzers for the audible indication warning. The sound level can be modulated or even muted by insulating the sound output cut out.
The casing and connectors replicate the OEM one.
Two versions are available, which with the OEM module cover the three possible use cases:
1. Full LED - suitable for LED bulb conversion for the front and rear indicators. Works with all Jass Performance LED TSI options at the front as well, as long as the rear bulbs are converted to LED.
2. LED + Incandescent - would work with LEDs at the front/rear and incandescent on the other end.
3. For full incandescent setup you should simply reuse the OEM flasher module.
Should you use the 1 option in setup 2 or 3, or the 2 in option 3, the indicators will work as supposed to, just the hazard switch might not function, due to the higher load.
