P21w 1156 Ba15s Led Bulb Super Bright White 6000K, with Projector 6W DC10-30V For Backup, Reverse Lights, Stop Drl Lights, Turn Signal Light, Rv Lights (Pack Of 2) [Energy Class A++]

The yellow indicator bulbs are super bright & have the ‘Original Parallel pins’ like any ordinary stop n tail , reversing light , & fog light bulbs , they are NOT the new offset pins which won’t fit the older vehicles .

These are were worth every penny. I have them in my VW T5.1 and are very bright and look great. They have been in for about a year and still work great so lifespan is super. They don't flicker and no errors on the dash. Only problem is I have these as DRL's, when i go through the tunnel I need to put headlights on so these go off to show up how bad my headlights are. So I need to get headlights now so they all look the same.

Received these today. Fitted with mods.1 Orange indicator bulbs did not fit, cause the pins should be off set 150 degrees, sanded the 1 pin off, squeezed the guide tabs in to secure the bulb. They are in nice & firm with silicon grease. These are very bright compared to the halogen. Only fitted these to the rear cause the CAMBUS does not like them, indicators flashing fast when only one side, slows when hazard is on, think I will get away with this, kept the old & spares in the back cubbyhole.2 Fitted the reverse bulbs, Magic, very bright compared to the old incandescent bulbs. did not take pictures.3 Cannot use the brake lights. The Zafira uses the same bulb for tail & brake, tail is dim, brake increases the brilliance, if you want to fit these you will have to do bench tests & do the maths for the load resistor, might just do this for fun.The Fog lights are dark red, so will have to get heat resistant colour to paint/spray/coat, should be a pen that that does this.I have made a word doc for my info, will try to copy it into here.CAR Driving lights:There are different types of bulbs.1 Off set high & low. BAY15D, P21/5W.2 Off set by angle, 180 degrees. BA15S, PW21W3 Offset by angle, 150 degrees. BAU15S, PY21W.4 Different colours, Red, Orange, Yellow & White or clear.Now for the fun part.Opel Zafira, same tail light has 3 different bulb types, now add different models with exact same tail light fitting, has different types of bulbs, just to make life fun, the LHAS bulb holder does not fit the RHS, on top of that there are different versions so the bulb holder does not always fit the old tail light assembly.NOTE Opel have CAMBUS, Ouch, so it detects the type of bulb, some LED’s will not work with the cambus. Also generic interior bulbs will blow the fuse cause they are not compatible.I have 4 different bulbs in the LHS assembly, same with the RHS assembly, BUT the RED bulb third from top is different between the RHS & LHS, so are the indicator bulbs. The RHAS assembly was replaced due to cracks & water leaks.My thoughts are they keep their sales up by making life difficult for us.Received 25 July 24, fitted with mods.Received these today.

Hoping this helpsFitted the ballast resistors & indicators are working good. 10 Ohm 50W fitted with adhesive heat tape that works well. very happy cause people keep tail gating me when I indicate to turn, I do indicate well in advance.Watch this space. There are loads of people telling me I'm wrong

As you can see from the pictures the bulbs are much brighter.The picture on the left has the new bulb on the right and the old bulb still on the left in the tailgate for ease of comparison.Night and day difference. The bulb on the right also brightens considerably when brake pedal is pressed, sorry no picture of this. I used to have fitted "380 Super Bright LED Car Bulb Halfords Advanced Twin Pack" but one of the bulbs went faulty, and these are cheaper. For clarification these are the bulbs I purchased from Amazon "1157 Bay15D P21/5w LED Bulb" as I know some people stated in the comments they couldn't get the brake and rear light combo working.

I bought a pair of these LED bulbs to replace my halogen dual filament brake lights in October 2021 and only one of them has failed on my car in November 2024.Well worth the money in my opinion and they are brighter than halogen bulbs, lasted longer than my halogens too (3 years so far on one bulb and the other is still going).The bulbs are quite good value overall I think but they should offer a free delivery service option as well that would take a couplle of extra days if your not locked into prime delivery as they kinda force you to pay an extra £5 for next day delivery which means I could have bought around 8 or more halogen bulbs from my local store for the overall price of these bulbs including delivery if your not locked into Amazon Prime deliveries.With that said, I have purchased a second set of these since my first purchase and would buy them again as long as the quality/value remains as is.

The biggest rubbish i have buy. Don't waste your money

They are very bright and no dashboard errors BUT unfortunately are flickering and don’t fit/secure due to positioning of the side pins - I’ll be returning and keep looking.

Much brighter than standard bulbs. I reversed down an unlit back alley tonight to drop something off at my daughters house and its a tight squeeze and these bulbs are so much brighter than the standard bulbs it was so much easier to see. It's a Transit Custom so you only have side mirrors to work with so bright reversing lights are essential. Great bulbs I will be buying spares.
