SpeedTech Lights Striker 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.

Easy install with suction but...it falls off after a week or so. Also it looks dim compared to the upper windshield speed tech lights. Maybe they used cheaper LED's. Not bright at all. It does have multiple patterns. I rate it 3/5.

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 have been using speed tech lights for years on my emergency vehicles. The LEDs are bright, the wiring is quality, shielded, and last the life of the vehicle, and the controllers are quality and work great. Even the feel of the buttons is quality molding and printing.If you need a different mounting system, they offer better (than suction cups) mounting systems for under $10 directly through their website which have always worked better for me.The directional arrow stick here is definitely worth the money, it also offers an auxiliary function for secondary lights.I use this lightbar regularly and it is in my opinion better quality than a wheelen light for 3 times the price.

I’ve added the light in summer and it worked great. When winter came and temperatures dropped the controller board (PCB) inside the bar couldn’t work properly anymore with low temps. The directional patterns stopped when 5 or more leds where activated. So it ended up a very weird unfinished laggy pattern.After a couple e-mails to stl with the ask for a new PCB they still charged a 170 shipping to the Netherlands. Even the warranty was still on I didn’t want to pay that amount of money for a product that I received with malfunctioning. So decided to remove the control board inside and made my own Signalmaster out of it and connected it to a smart siren SS2000SM. Now works really fine. LEDs modules bright but never trust the control boards from STL.

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.

Works as intended, the wiring harness was kinda short, but I just extended it which does not void the warranty.
