OPP ULITE 1157 BAY15D Led Bulbs Error Free Canbus Built In Resistor White/Amber Turn Signal Lights Switchback LED Bulbs P21/5W 2057 2357 7528 12V 360 Luminous (2 PCS)

After a previous pair of LED indicator bulbs failed so miserably (out of the box), I returned them and gave these a try following some good reviews.Were the reviews right? Oh yes siree! These are absolutely perfect!Brightness: Bright, clean and deep amber. Crisp output and they look absolutely stock. Bright enough to communicate direction intention, but not so bright (as some are) to cause dazzling or white out. It's an area which has to be spot on, and these hit the nail on the head.Ease of installation: Any one with half a brain can change car bulbs, unless you are unfortunate enough to own a Renault, in which case you'll probably have to remove a bumper. These bulbs are slightly shorter than a stock incandescent 21w bulb, and the circumference is the same. Pins are 150 degrees as they should be for replacing an amber bulb. Easy peasy!In use: My car uses the front indicator bulbs as sidemarker lights (it's a BMW, and it's built into all BMWs, but one has to use BimmerCode or something similar to access the settings), so a consideration was temperature. LEDs get HOT, VERY HOT. These however have cooling fans in the head So the temperature shouldn't be a problem. Time will tell on this.Hyperflash?: Not on my BMW, although do bear in mind that I used BimmerCode to set the system for LED indicator upgrades to reduce the sensitivity of the feedback loop to the ECU. Most cars you won't need to, but if you have a BMW you'll know just how sensitive the million sensors are to anything even slightly wobbly. These purport to have resistors to 'trick' the CANBUS system into believing the load is equivalent to an incandecscent bulb, but as I can't say yay or nay for sure, you'll have to suck them and see. Don't actually suck them.Conclusion: Buy without hesitation. The build quality alone will tell you what ace little bulbs these are. When you see the result you'll be over the moon. I don't know about longevity yet as I've only fitted them today, but I have a sneaky suspicion that they'll last the lifetime of the car.Top stuff!

works fine in Megane 3, no hyper-flashing

Good product but just too bright

Very bright white led on side light and main beam but the colour is orange for daylight running light which I was hoping it would be white!

These bulbs do exactly what they say, bright no faults and no hyper flash. This was my fourth attempt at getting LEDs that worked properly. The cheaper ones just don't work properly these do and are worth the money. I can't comment on longevity though because I have just fitted them but so far I am impe

Excellent product so bright, and they certainly look the business

These are plug and play as far as canbus goes, no error messages as advertised. The output is high and emits a super bright deep orange.Very happy with this product

The media could not be loaded.  I had bought them beforehand which I had no issues with but I had to return them due to financial issues, I had bought them again and now 2 of them are making sounds? I don’t think a light bulb should be making any sound
