2002 Buick lesabre limited headlamp LED conversion

[TheChristian]

I installed the new hb3 high beam and hb4 low beam LED and also a can bus for each light but the lights don’t come on , what did I do wrong ?

 

[TheChristian]

While answers pending and being impatient I removed the can-bus decoders and both high and low beams work just fine with no flashing or flickering , I really need to stop asking ai for advice !

How can the lights, both high and low, work without the hyper flash? I only did my low beams because I thought doing the high beams caused hyper flash.

I never had an issue with LED headlights (Retrofit) on my 2001. Why the can-bus? If anything, a resistor would be used on flashing lights such as the brake lights.

My LED's were plug N' play.

I never used the can-bus with my led conversion and have no issues hi or low beams. Some of the 1st gen led conversions needed them but anything in the last few years work without them.

I have the 9005 Auxito bulbs for low beam so you're saying the auxito 9006 high beams probably will work?

Yes will work without flickering but some have issues retaining the DRL function. Auxito makes cheap and expensive bulbs so check there website

Sorry if this is dumb but are the cheap ones bad and the expensive ones good?

 

[ulycyc]

No, the expensive bulbs have more options, higher candlepower and maybe longer life. You need to look at there website and compare what bulbs you have now.

 

[2000ltd]

I got these. Not the most expensive but for a headlight bulb they are kind of high. I'll go to their site and compare mine with their other ones. I just bought the most popular light aliexpress had.

I just compared all there bulbs and out of about 15 different models I chose the second best. It is the m5S bulb and btw on auxitos website they sell it for $80 and on aliexpress it was $22.50
