1. I have bought the DRL controller as well. The switchback from indicator to DRL feels very OEM. 2. Brightness is good. 3. Because of the DRL controller, after switching off the car, the DRL stays on for a few seconds like follow home headlights. This is a great aspect I found.

Very interesting and awesome product. LED drls and turn signal indicators built into the same bulb. Perfectly compatible for Ford Figo and Aspire. Almost plug and play installation. Except the resistor must be mounted over metal part, so that could be tricky. Used separate fuse tap cable to take power from fuse box. DRLs come on when car is in ignition and started and they really upgrade look of headlights. No hyperflashing at all of indicator (resistor prevents it well). Overall value for money. Have to see the durability. Thanks Durvient.

Bought, installed and loved by several of our S-cross community members. It’s an amazing addition.
The led is working properly. Good quality
Feels premium. Fit is a bit loose for VW Vento/Polo headlights but that can be easily overcome. Overall finish is premium and OEM. Suggested to buy with DRL controller so that no OE wiring will be needed to be tampered with.
