HellaOptilux H71070682 XY Series H4 Xenon Yellow Halogen Bulbs, 12V, 60/55W, 2 Pack

Easy to install.Blue light is bright

Brightness is down but I drive mostly during the day so I use them primarily as day time running lights. The are adequate for night driving though. The are brighter than normal bulbs. I love the look though. They are definitely high quality as most Hella stuff is.

Posted a pic the HELLA are the top pic...Got these for me 03 tundea after buying LED headlights and fogs and spening $135 , hated the light pattern so decided to go alot cheaper and buy these and wow! The white color is amazing has a slight blue when looking at the bulb but very bright and clean white....will check back in at a later date but right now very happy with these

On my 2nd set. I like the color and brightness the boost in watts is great for some extra lumens without any damage to the stock housing. Great option if don't want to hassle with hids or buy over priced LED bulbs. Only downside is they don't seem to last a really long time so buy an extra set for a backup.

Cheaper than the PIAAs that I was thinking about originally and made by a known (German) quality manufacturer, these bulbs are good quality made by Hella in Korea and sold in the US.First impression after I got the delivery were all good, lamps and packaging are on the same quality feel level as the Phillips Motovision that I used to have in the bike before. Bulbs came with DOT and E mark certifications.After several months and thousands of miles commuting on the motorway (sorry, freeway in US lingo) and through inner city mayhem I noticed that car drivers do recognise me earlier, I have much less near misses than before! I really can't believe it how great the effect is, the car drivers even do make more space for me now! Of course, there still is the occasional inattentive driver that does cut me off, but it is neither as often, nor as sudden as before.My theory is that in the sea of headlights car drivers can see in their mirrors, I stand out because of the yellow colour. Very occasionally I do see a car with yellow headlights and I see how much of my attention that draws to it- its just outstanding!The only slight downside is that all the white coloured road markings, reflectors and signs now appear yellow in the dark. I do also think that the low beam would not be ideal to ride fast(ish) on a rural roads at night, both due to the colour and because its not as much light output as the best premium (white) bulbs. My guess is that Hella put more effort in making these glow yellow than in getting more lumens out of them.For my riding though, 99% city and motorway, where the purpose of headlights is more to be seen whilst filtering through traffic than to see with its beam, the yellow Hella bulbs are perfect.
