SpeedTech LightsStriker TIR 8 Head LED Traffic Advisor Light Bar for Emergency Vehicles/Strobe Directional Warning Light

This traffic advisor bar is bright and shows up well during the day and at night. I volunteer for litter removal along roadways and the light is visible far away and is safe to use to advise motorists to either slow down or merge left / right. The light bar is also compact enough it doesn't block the view out the rear cab window of my truck.Mounting:The bar mounts easily on any vehicle type and can be removed easily by pulling a tab on the suction cups. Finding traffic advisor bars to mount on truck cab windows can be hard since most products are made for sloped / angled windows. The SpeedTech lights comes with an included bracket and suction cups for a 90-degree mount that were perfect for a truck cab window but there's also a 360-degree suction cup mount you can buy separately if needed.My only slight complaint but won't dock a star for is that the suction cups were kind of difficult to slide onto the metal brackets. Had to use pliers and struggle with the back part of the suction cup back and forth over and over again to get them to pop in. Since there are 3x 90-degree brackets with 3 suction cups each you'll have to do this 9 times during install. At least you'll need to do this once and you'll know the suction cups will be real secure and never pop out of the mounting bracket.Control Box:The control box that came with the lights is simple and easy to use. It's compact enough it could fit inside a cup holder. The buttons have a nice backlight to them so you know which mode the bar is in at any time. It has a nice option for a switching the flashing speed from slow to fast.I like how you can easily jump from a flashing mode to a merge indicator with just one button push. The last light bar I had just had a single switch requiring you to cycle through 15x different light patterns one by one.

I have owned these for just over 1 year, paired with the Super Takedown Raptor TIR visor lights. Lights have always worked as intended with no issue and have been bright and highly visible even through tinted windows during the day. Day or night, I have never had a problem with these lights and they have always been highly visible when on the side of the road. The only problem I experienced with these was attempting to use the suction cup mounts so I wouldn’t have to make any modifications to my car. Apparently, my Ford Explorer’s windows are just curved too much for the cups to hold properly. I tried many different options for mounting, but eventually just rigged up my own little mounting solution to address the issue. Anyone using actual mounts that involve drilling and attaching brackets should have no issue, I just didn’t want to modify my actual car. Still, it wasn’t too difficult to figure out and I’ve had absolutely no issue with the lights themselves. STL’s customer service was also great when I purchased another product from them and the control box wasn’t available. I was actually sent a better control box that worked with the other product AND this one together, which worked perfectly for me. Overall, though the suction cups sucked and I didn’t want to use brackets, these were still quite simple to install and have been a great product I can always rely on.

Cons:1. I had to superglue/krazy glue the suction cups to my windshield to keep it from falling every 20 minutes.2. I don't know if this was a glitch but at one point the last LED on the traffic arrow mode stopped working and to fix it I had to turn the vehicle off and back on, very odd but thank god it finally worked.3. The stock cable length without extensions BARELY reached the front of my vehicle (2011 Crown Vic P71)4. I received no instruction guide and the suction cups really hurt to put into the bracketsPros:1. Very bright even past 3% tint2. Video on how to use the control box is very helpful3. Would recommend this for professional use by law enforcement any day3. The LED's barely reflect (while it is off) back to any light shone through the windows which is great if you want it to be stealthy4. Very sturdy and better than the cheap ones and very much worth the price.

I ordered this and am very happy with it so farTo note however, some assembly is required and it can be a bit confusing.The mounting brackets come in pieces; the bracket themselves, 2 guide bolts, 2 washers to put under the guide bolt so it slides into the track, 2 nuts to secure the bolts, and 2 unknown washers or something. Also I found no way of keeping the brackets from sliding about unless you have to tighten the nuts to the extreme.The visor comes with 10 screws (6 small, 4 long), 2 endcaps, and the visor itself. To assemble the visor don't make my mistake and misread the instructions. I thought you had to uninstall the stock endcaps when in reality the visor endcaps just go over the stock ones. The 6 small screws go into the small holes on the endcap and screw into the grooves of the visor and the 4 long screws go into the endcaps of the bar THROUGH the visor endcaps. I will say the other reason this got a 4 instead of a 5 is because one of the long screws had a flat tip (the cross for the screwhead was too far surfaced to use the screwdriver).The control box works perfectly as well, though i can not remove the harness now. it is too snug. Gonna be trying again so I can mount the box without the wires in the way. I have not tested the AUX function yet, I will need to splice my current dash light (manufactured by another company) into the aux wire. Hopefully I can cut the Aux cable down to size cause it is too long since the dash light already has a long wire about the same length as the aux.Aside from the assembly I like it, though it will not fit behind my rear seat headrests like I'd hoped. The depth (from front to back) is too wide. Perhaps if I raise the headrests it will work. It is very bright, in fact so much so the visor is pretty much required so my truck cab isn't a disco.

Pretty good light my only complaint is if you use the controller the only way to turn off patterns is to hit the power button you can push the same button to turn the selected pattern off and the wire connector is on the right side at the end so mounting is hard. I’ll be hooking it up to a feniex 4200 mini instead. But other than that pretty good light very bright
