stedi light bar
Review by Parkesy
What a great product, I had a small issue with my light and stedi replaced it straight away including freight. Unreal (Posted on 21/03/2018)
Review by JK
I live in the foothills of Colorado at 8,500ft and needed some throw for my 06' Tundra to help avoid hitting elk, mule deer, etc. on the dark mountain roads I drive daily.

I also wanted some auxiliary lighting for overland/off-road trips and I had never heard of Stedi until I watched some Ronnie Dahl videos on Youtube.

I'm blown away by how much light the st3k puts out. The pictures and description don't do it justice. The harness, build quality and connections (e.g. Deutsch waterproof) are top notch, especially at this price point. Additionally, the H4 connection to the headlight with integration with the high beams is brilliant, simple and was the primary driver for this purchase.

I'm really excited to run this on some upcoming overland trips this summer here in Colorado, Utah, etc. I'll follow up with a more long term review. (Posted on 26/01/2018)
Review by Stephen
I purchased for my 03 subaru forester which over the years has lost its reach with the stock high beams. the st3k was a perfect fit, sits just below my number plate and wow, what a reach. i can highly recommend the product for quality and the company for service. i did upgrade the stock kits rocker switch to match my interior which was a personal choice but also a top pick!

Well made unit
Review by Review by Nick
Bought this light bar for my Toyota Hilux. I was impressed on how well made this unit is. Easy to fit onto my Nudge bar and the wiring harness supplied was excellent and straight forward to hook up with instructions provided. The light from this unit is very bright and white in colour. would recommend to anyone. (Posted on 13/11/2017)

VF commodore ssv
Review by Andrew
I purchased this led lightbar to use on my VF series 2 ssv to place behind the grill, the low profile height of 63mm is the best I have seen on the market, others have used standard height ones and have had to modify the mounts so as to lower the bar, also I was able to slip the bar in behind the grill from above and not have to remove the whole front end to attach it, whilst the light produced from it is better than the standard high beam, it still could be better off to the sides (I think it looses some from being placed behind the grill - not the light bars fault) it certainly looks bright when you are looking from the front - so oncoming traffic should know you are there, I will be adding led high beam globes next to assist with this. do I regret purchasing the bar - not at all, do I recommend it, yes, great adjunt to my lighting system - it can only assist in the spotting of the kangaroos in my area.

I just fitted one of these to the lower air dam of my ford everest.

Such an impressive light for the size and cost, a quality unit through and through right down to the wiring harness!

Prior to purchasing, My questions were answered promptly and professionally, and shipping was super-fast!

Top job guys! (Posted on 27/07/2017)
