Review on CEC Industries Electronic Flasher Compatible Exterior Accessories and Body Armor by Kyle Kriglstein

Installed LED turn signals on my 94 LS400 (UCF10) but when there was a sudden power outage they started flashing. I didn't want to add a built in resistor (I'm not a fan of major modifications to stock electronics) so I went down the route of replacing the electronic turn signal relay. With the LS400, it's not easy work, but it's worth it. I have LED turn signals that stop flashing. The only minor thing I noticed is that when the turn signal is first activated, there is a SLIGHTLY longer initial "on" pulse before the pulse rate normalizes. This is negligible, but maybe 3/4 second more than the 1/2 second that happens with the stock Toyota flasher relay. As soon as the turn signal is extinguished, it stops. Some people report hearing blinking "clicks" for a second or two after canceling, but I haven't experienced that. All in all, recommended if you convert your turn signals to LED and don't like messing around with the standard electrics.
