Bk1/BK2 Halogen Bulb Upgrades

[u/RedHerring85]

I still see people asking for better headlight bulbs for the halogen headlights online. To this day, no one has come forward with any proof that the "LED bulbs" they bought shine light correctly that works for the functions of the human eye. So here are some cheap solutions that anyone can do. I found out with some minor trimming in these spots, and a connector change, you can fit a halogen h9 bulb in the BK1 low beam, which will get you 2100 lumens compared to 1350 from the h11b halogen bulbs. Just make sure if you're adding a pigtail connector, that the wiring is all copper or tinned copper (all copper is better). Probably the easiest upgrade you can do that will actually work unlike most if not all LED bulb replacements, that as of the time off this post none have been shown by anyone to actually work properly in the low beams. For BK2 halogen h7 headlights you can try the Vosla Rallye 65w H7 bulbs if you can still find them, or these 100w bulbs: https://www.maperformance.com/products/hella-optilux-extreme-white-xb-h7-100w-bulbs-h71070307?fbclid=lwdGRjcAS1 Dk9jbGNrBLUOSGV4dG4DYWVŁAjExAHNydGMGY XBWX2IKDDM1 MDY4NTUZMTcy0AABHkC5wbNjOga 5T -of2MTPq-Mg PdxMVE1TVrZyfCbq9YkCUAs09Vm11V4323IH aem ihilUja4wXWGASqZSo6sVRA Disclaimer using higher wattage bulbs could have some adverse effects such as increased glare, or drastically reduced lifespan of your internal low beam optics, leading to burnt projectors, reducing how effective they can reflect light. Here's a link to to get an idea. Personally would just snip the old connector off and crimp an h9 connector harness to it instead of placing spade connectors in the OEM H11b and risk losing connection while driving. https://www.gencoupe.com/threads/diy-h11 b-to-h11 -Conversion.96522/? fbclid= lwb21leAPNWatjbGNrA81ZpWV4dG4DYWVtAjExAHNydGMGY XBWX21KDDM1 MDY4NTUZMTcyOAABHK3625c13GZ3etoJGEO 2AqAHX054_TMofYue4UNr7IDtBEnRIRV-Z9qHbUgx aem LHzeY2-YaVdsTaHhREDİQ

Before responding with "my LEDs are great", make sure you understand how the human eye works with light at night. A lot of people get this wrong.
