Review: Bright (but not "4800LM"), work great - Bought these on a whim to compare them with the excellent DDM bulbs I've had in my Volvo backup lights for a little over 2 years now. Those have been an incredible improvement over the stock bulb, and I was hoping I might find something even brighter. Despite the ridiculous claim of 4800 lumens in the listing for these HSUN bulbs, they are still very bright and right on par with the DDM bulbs (listed as 800 lumens). However, these are a bit cheaper which is nice, and they seem to work just as good as the DDM. The bulb shell is pretty much identical between the two, only the LED chips are different, and since this bulb style is limited to 3.5w I suppose you can only get so many lumens/watt out of an LED. These are definitely worth purchasing and fit right into the original socket with no problems.
Review: Bright Reverse LED, Works With CANBUS - Lights were a perfect fit for my vehicle. Didn’t cause any CANBUS issues. Very bright white LEDs that make seeing at night much easier. 4/5 stars because the packaging is of cheap Chinese origin and the LEDs don’t seem “high quality” and will probably fail within a year. $20ish is high for these LEDs, but if you need bright white replacement LEDs that don’t conflict with CANBUS, these will get the job done.

### ⭐⭐⭐⭐⭐ Bright (but not "4800LM"), work great
*by C***S on May 19, 2021*

Bought these on a whim to compare them with the excellent DDM bulbs I've had in my Volvo backup lights for a little over 2 years now. Those have been an incredible improvement over the stock bulb, and I was hoping I might find something even brighter. Despite the ridiculous claim of 4800 lumens in the listing for these HSUN bulbs, they are still very bright and right on par with the DDM bulbs (listed as 800 lumens). However, these are a bit cheaper which is nice, and they seem to work just as good as the DDM. The bulb shell is pretty much identical between the two, only the LED chips are different, and since this bulb style is limited to 3.5w I suppose you can only get so many lumens/watt out of an LED. These are definitely worth purchasing and fit right into the original socket with no problems.

### ⭐⭐⭐⭐ Bright Reverse LED, Works With CANBUS
*by S***Í on August 20, 2020*

Lights were a perfect fit for my vehicle. Didn’t cause any CANBUS issues. Very bright white LEDs that make seeing at night much easier. 4/5 stars because the packaging is of cheap Chinese origin and the LEDs don’t seem “high quality” and will probably fail within a year. $20ish is high for these LEDs, but if you need bright white replacement LEDs that don’t conflict with CANBUS, these will get the job done.

### ⭐⭐⭐⭐⭐ Awesome Reverse Lights...
*by K***Y on September 27, 2020*
