Can't comment on sliders as I don't have them.
What I do have are drop bars that (unfortunately) I've used a time or two
I sprung for the Weiser Technik's for the rear as I was not able to come up with a better (but cheaper) solution (Amber turn & Red stop).
I wish they featured a continuous on low powered Red (Running) light & they may in the future.
NOTE: The turn signal housings do not appear to be fully waterproof so I took precautions.
I blocked off/sealed where the wires leave the assembly as I figured this was an exit point for air/moisture that might be drawn in via Venturi effect (on the rear).
I also applied a thin & narrow swath of clear silicone sealing the clear lens from the black housing. I used tape to limit the swath. I made sure that the weep holes were not blocked on the underside of the lenses.
For the front turn indicators, I was able to cram a set of (extremely) modified

I had handgards that I installed two 3w forward faceing & one 1w side facing Amber Oznium

These are run through a Skenedesign turn signal modulator
https://www.skenelights.com/online-store/IQ-250-A-TS-Front-Lighting-Controller-with-Alert-%26-Turn-Signals-p80222667 that creates a nice flickering effect (PWM) that increases conspecuousness. NOTE: I found that this PMW effect causes a noise in the DC/DC power supply reminiscent of high tension power lines crackling in humid conditions but no othe negative effects observed.
I also fabricated an 8 Oznium bolt array to the bottom of the Givi trunk rack giving rear & side Running, turn, & brake indications. I ran the stop indicators through a flasher controller

Also up front I have a pair of Selective Yellow 10w fog lights.
I fabricated T brackets out of scrap heavy gauge sheet metal angles left over from a window trim (curtains) project.
I mounted the brackets to the fork tube protector attachment points via standoffs & longer screws.
I run the power along side of the brake/ABS lines & used the hollow axle bolt to get it to the other side. (A bag of 4" black zip ties & a real zip tie gun made all the difference).
I replaced the incondesent headlight & running light with a LED to free up some electrons for all the other light.
I installed two Hella (Hi/Low) horns in the front crevices of the faux tank.
For the horn relay, I used a DPST relay & ran the power for my elect shirt through the N.C. contact.
That way I limit the power draw when applying the horn(s) (3 of).
On my ICE bike (2003 BMWR1150RT) I installed reflective tape to the rear of the side bags that's black until hit by light.
After being told someone almost hit my bike in a parking structure, I applied alternating Red/Yellow staggered strips off 3M 1" reflective tape.
I alternated reflective tape & removable masking tape to achieve the staggered effect.
I have handgards so I was able to tie a heavy duty string in a loop around the right side that resembles a tassel
I'm able to apply the front brake & loop this knot over the lever to hold the brake.
I replaced the oddball turn flasher with a solid state unit & had to swap the +- on the bikes socket.
